18acfe6495 Revert the extension of with-decorator to setv
This is no longer necessary now that `defn` always produces a `FunctionDef`.

To compensate, I've made small edits to two contrib modules and reverted a small test change.

7c203abe4d Fix bug with unset __name__ of one-line functions
The bug was a regression that I introduced in #1228.

I've created a new special form named `fn*` that works like the old `fn` (that is, it always creates a `FunctionDef`). Since this is intended only for internal use, like `with*`, I haven't documented it.

e4a7b317e1 Make fn work like lambda and remove lambda (#1228)
* with-decorator: Allow a `setv` form as the form to be decorated

This feature is of dubious value by itself, but it's necessary to allow `defn` to create a lambda instead of a `def`.

* Make `fn` work the same as `lambda`

That is, allow it to generate a `lambda` instead of a `def` statement if the function body is just an expression.

I've removed two uses of with_decorator in hy.compiler because they'd require adding another case to HyASTCompiler.compile_decorate_expression and they have no ultimate effect, anyway.

In a few tests, I've added a meaningless statement in `fn` bodies to force generation of a `def`.

I've removed `test_fn_compiler_empty_function` rather than rewrite it because it seems like a pain to maintain and not very useful.

* Remove `lambda`, now that `fn` does the same thing

ed930edefe Allow keyword args in method calls before the obj (#1167)
Unlike Python, Hy allows the programmer to intermingle positional and keyword arguments. This change removes an exception to that rule for method calls, in which the method callee always had to be the first thing after the method. Thus, `(.split :sep "o" "foo")` now compiles to `"foo".split(sep="o")` instead of `HyKeyword("sep").split("o", "foo")`.

I don't see why you'd put this in the standard library. I guess it could be useful for when you're maintaining a library and you want to change the name of a function or macro but keep the old name around for a while so people's code doesn't break immediately. But that's a pretty limited purpose.

* put back import getargspec

* Give better error message on failed macro expansion

Better error messages work most of the time. In cases where there are
parameters that aren't valid in Python, error message shown is rather
ugly. But this is better than no error messages at all and such
macros with strange parameter names are rather rare.

* fix flake8 errors

14fddbe6c3 Give require the same features as import (#1142)
Give `require` the same features as `import`

You can now do (require foo), (require [foo [a b c]]), (require [foo [*]]), and (require [foo :as bar]). The first and last forms get you macros named foo.a, foo.b, etc. or bar.a, bar.b, etc., respectively. The second form only gets the macros in the list.

Implements #1118 and perhaps partly addresses #277.

N.B. The new meaning of (require foo) will cause all existing code that uses macros to break. Simply replace these forms with (require [foo [*]]) to get your code working again.

There's a bit of a hack involved in the forms (require foo) or (require [foo :as bar]). When you call (foo.a ...) or (bar.a ...), Hy doesn't actually look inside modules. Instead, these (require ...) forms give the macros names that have periods in them, which happens to work fine with the way Hy finds and interprets macro calls.

* Make `require` syntax stricter and add tests

* Update documentation for `require`

* Documentation wording improvements

* Allow :as in `require` name lists

4b0296d257 Don't check the type of arguments to inc, odd?, etc.
This allows them to be used with numeric types that aren't built in, such as NumPy arrays. Because Python uses duck typing, there's generally no way to know in advance whether a given value will accept a given operator. Of course, things like `(inc "hello")` will still raise a `TypeError`, because so does `(+ "hello" 1)`.

8d2143177e Overhaul macros to allow macros to ref the Compiler
This allows macros to take a keyword dict containing useful things by
defining a keyword argument. This allows us to pass in new objects
which might be handy to have in macros.

This changeset refactors module_name to become `compiler`, so that we
can pass the compiler itself into the macros as `opts['compiler']`.

This allows the macro to both get the macro name
(`compiler.module_name`), as well as use the compiler to build AST.

In the future, this will enable us to create "super-macros" which return
AST, not HyAST, in order to manually create insane things from userland.

For userland macros (not `defmacro`) the core.language `macroexpand`
will go ahead and make a new compiler for you.

apply now mangles strings and keywords according to the Hy mangling
rules (by using the same function, now imported from
hy.lex.parser). With this change, if the dict passed to apply has
keywords, strings or quoted symbols, they'll get mangled, to turn them
into proper keys.

This only works for the cases where the keys are directly in the apply
params. A previously deffed dict, or key through a variable will not be
mangled.

This closes #219.

c89865aaf0 defclass should add an implicit nil to --init-- functions
To make it easier to write --init-- functions, defclass will now check
any (setv) expressions (and its property list), to find any --init--
declarations, and append a nil to the end.

b92049d119 Allow defclass to have properties/method with built-in names
To allow classes to have methods that match built-in names, yet, still
disallow them outside of defclass, keep an internal state whether
builtins are allowed in the current context.

By default, this is false. But defclass will set it to True when it
compiles its body, and set it back to the previous value when it's done
with that. We need to set back to the previous value to allow nested
defclasses to work properly.

This closes #783.

defclass reimagined
defclass now has a new syntax:

 (defclass Name [BaseList]
   [property value
    property value] ;; optional

   (defn method [self]
     self.property))

Anything after the optional property list (which will be translated to a
setv within the class context) will be added to the class body. This
allows one to have side effects and complex expressions within the class
definition.

As a side effect, defining methods is much more friendly now!

016557deab reader macro #@ for with-decorator
The `with-decorator` special form is not the most ergonomic—this commit
introduces a new builtin `#@` reader macro that expands to an invocation
of `with-decorator`. To support this, `reader_macroexpand` is made to
also look in the default `None` namespace, in imitation of how
regular (non-reader) macros defined in hy.core are looked up. The
docstring of `hy.macros.reader` is also edited slightly for accuracy.

This in the matter of issue #856.

ef079d5e08 implement keyword-only arguments
Python 3 supports keyword-only arguments as described in the immortal
PEP 3102. This commit implements keyword-only argument support for Hy
using a `&kwonly` lambda-list-keyword with semantics analogous how
`&optional` arguments are handled: `&kwonly` arguments are either a
symbol, in which case the keyword argument so named is mandatory, or a
two-element list, the first of which is the symbolic name of the keyword
argument and the second of which is its default value if not
supplied. If Hy is running under Python 2, attempting to use `&kwonly`
args will raise a HyTypeError.

This effort is with the aim of resolving #453.

fb98bf58c4 *args and **kwargs no longer have own args in Python 3.5
Python 3.5's PEP 448 ("Additional Unpacking Generalizations") allows the
iterable- and dictionary- unpacking operators to be used more than once;
the implementation (see https://hg.python.org/cpython/rev/a65f685ba8c0)
gets rid of the optional `starargs` and `kwargs` arguments to `ast.Call`
and `ast.ClassDef`, instead using `ast.Starred` and `ast.keyword`
objects inside of the normal `args` and `keywords` lists,
respectively. This commit allows Hy's `apply` to work correctly with
this revised AST when running under Python 3.5.

2ad2d5a418 fix keyword lambda values by retaining statements in Result
As reported in issue #748, there was a bug in which passing a lambda
as the value of a :keyword argument would fail—

$ hy --spy
hy 0.10.1 using CPython(default) 3.4.0 on Linux
=> (sorted (range 10) :key (fn [x] (- x)))
from hy.core.language import range
sorted(range(10), key=_hy_anon_fn_1)
Traceback (most recent call last):
  File "<input>", line 1, in <module>
NameError: name '_hy_anon_fn_1' is not defined

The function call would appear in the generated AST without being
preceded by the appropriate function definition corresponding to the
anonymous function argument value in the Hy source, causing either a
NameError (as in the example above), or erroneous reuse of whatever
function was already pointed to by the `_hy_anon_fn_` name referenced
in the list of keywords passed to `ast.Call`.

This commit aims to fix the problem by handling it in same way that
the expression/statement gap is bridged many other places in the
compiler, by adding the compiled value of the keyword argument to the
Result object being built during `_compile_collect`, with the
understanding that any Python statements implied by the argument value
will be appropriately preserved therein.

0dbf2126cf adds support for Python 3.5 infix matrix multiplication
Python 3.5 will have a new commercial-at infix operator with the magic
methods __matmul__, __rmatmul__, and __imatmul__, unused as yet in the
standard library, but intended to represent matrix multiplication in
numerical code; see PEP 465 (https://www.python.org/dev/peps/pep-0465/)
for details. This commit (developed against Python 3.5 alpha 3) brings
support for this operator to Hy when running under Python 3.5 (or,
hypothetically as yet, greater). For Hy under Python <= 3.4, attempting
to use `@` in function-call position currently results in a NameError;
this commit does not change that behavior.

This is intended to resolve #668.

6b3c552df4 Better error messages for fn/defn w/o arglists

emit a more descriptive error message, rather than an ugly traceback.

Fixes #716.
