e588b4928d add defmacro! and fix macro expansion error message (#1172)
* added defmacro!

* revert #924

#924 had an error and should never have been merged in the first place. (see #903)

* put back import getargspec

Without the `formatargspec` this time.

* 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

* Minor English improvements

Old defmulti has been renamed to defn and extended to detect when it is

ed8e37da62 Burninate the synonyms true, false, and nil
Per the straw poll in #908, as an alternative to #1147.

Now you must use `True`, `False`, and `None`, as in Python. Or just assign `true` to `True`, etc.; the old synonyms aren't reserved words anymore.

584a40d9c0 Update tests to work with Pytho 2.x
In Python 2.x (range 10) is mapped to xrange(10) in Python
terms. However, xrange doesn't support slicing, which caused tests to
fail. By forxing xrange into list, we have slicing available.

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.

f24daa7ef9 defreader: Allow strings as macro names
This makes it possible to use strings as the macro name argument to
defreader, which in turn makes it possible to define reader macros with
names that would otherwise result in parse errors.

Such as `#.`.

This fixes #918.

f4afb0ca7e variadic if
The `if` form now supports elif clauses.
It works like `cond` but without the implicit `do`.
The old `if` is now `if*`

variadic lif now supports "ellif" clauses.

Update if-no-waste compiler to use `if*` properly.

(Sometimes one character is all it takes.)

0a942a069f Support one-arity comparison operators too
Comparison operators such as =, !=, <, >, <=, >= should support a
one-arity version too, and return true in those cases (except for !=,
which returns false).

32f5d5dea7 Drop a set of brackets from with.
This changes with syntax from (with [[x (expr)] (expr)] ...) to (with
[x (expr) (expr)] ...). Should have no ill side effects apart from the
syntax change.

9f88e07e1d Drop a set of brackets from let.
This changes let to use a flat list of symbol-value pairs instead of a
vector of vectors. One side effect is that (let [[a 1] z]) is not
expressible now, and one will explicitly need to set a nil value for z,
such as: (let [a 1 z nil]).

Closes #713.
