7bf2901364 Ban (except)
It's rarely useful, because it catches all exceptions, but it doesn't let you do anything other than return `None`. You can still get the same effect with `(except [])`.

84e1c65bcd Improve checks inside defclass
We need to make sure we're looking at HyExpression when trying to
determine if we're rewriting an __init__ expression.

cf7ff802c9 Make hy.compiler.builds more flexible
I removed the "Hypster" error message and the test for it because it can only catch compiler bugs that should themselves be caught by Hy's tests.

ecc974de1e Implement Python 2 exec

5eb928356a Overhaul semantics of binary operators (#1261)
I've added shadow versions of many operators that didn't have one. And, I've changed the behavior of various binary operators with more or fewer than 2 arguments to make the shadow and real versions more consistent and to make the behavior more logical in either case. For details, see the additions to NEWS and the new file tests/native_tests/operators.hy, which simultaneously tests shadow and real operators.

Although there are a lot of changes, I've put them all in one commit because they're interdependent.

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

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.

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

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).

This closes #949.

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.

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.
