16e908d56e In order to fix #608, we need to know which symbols can't be assigned.
Python has the keyword.iskeyword method we can leverage for Python
keywords, but we also need to address Hy builtins like 'get' or
'slice'.

And to make behavior compatible with Python 2 or 3, we also make
a special case to prevent assignment to False, True or None as
well as the Hy versions: false, true, null, and nil.

For non-Hy modules, we also check to make sure the symbol is not
part of the compiler. This allows shadow.hy to override "+" but
prevents general use from re-defn-ing 'get' or 'do'.

ea5eba5916 Second part of the fix for yield inside a try-finally
As noted in #600, Python 3 allows a return inside a generator
method, that raises a StopIteration and passes the return value
inside the 'value' attr of the exception.

To allow this behaviour we simple set 'contains_yield' while compiling
'yield', thus allowing a return statement, but only for Python 3. Then
when compiling the try-except, we check for contains_yield to decide
whether there will be a return.

This allows code like:

(defn gen []
  (yield 3)
  "goodbye")

to compile in both Py2 and Py3. The return value is simply ignored in
Python 2.

hy2py in Python 2 gives:

def g():
    yield 3L
    u'goodbye'

while hy2py in Python 3 gives:

def g():
    yield 3
    return 'goodbye'

Turns out return in yield started in Python 3.3

b56a03750f revert yield-from test
Yield-from was introduced in 3.3, so we have to catch the compile error that's raise in 3.2. :(

277028cdd5 Remove HyLambdaListKeyword from the parser
It's not a syntactic element and doesn't belong in the parser. Parsing
lambda lists is now handled by the compiler alone.

8e173937c3 Add shadow.hy to core
This new core module allows us to shadow the builtin Python operators so
they may be passed to sequence functions that expect functions:

    => (map / [1 2 3 4 5])
    [1.0, 0.5, 0.3333333333333333, 0.25]

15ad6cb998 defmacro/g! and HyObject#startswith
Currently, defmacro/g! doesn't respond well when it comes across a
HyObject that doesn't respond to the instance method startswith (e.g.
HyInteger, HyFloat, etc.). This updates defmacro/g! to be a little
safer when searching for the gensyms it needs to create.

caa53fb095 Tests for explicit exception chaining
This also breaks out the PY3 only tests into their own file.  We need to do this because raise from is a syntax error in PY2, so we can't rely on the previous hack of catching a HyCompileError - it would compile fine through Hy and then be a syntax error in Python.

8e4b21103c Reimplement some built-ins in terms of the standard library.
As a result:

  * functions such as `nth` should work correctly on iterators;
  * `nth` will raise `IndexError` (in a fashion consistent with `get`)
    when the index is out of bounds;
  * `take`, etc. will raise `ValueError` instead of returning
    an ambiguous value if the index is negative;
  * `map`, `zip`, `range`, `input`, `filter` work the same way (Py3k one)
    on both Python 2 and 3 (see #523 and #331).

3f9ae9122e Raise exceptions when no handlers are provided.
Also small DRYing in try handling.

Previously, writing a bare (try (foo)) would invoke Pokemon
exception catching (gotta catch 'em all) instead of the correct
behavior, which is to raise the exception if no handler is provided.

Note that this is a cute feature of Hy, as a `try` with no `except`
is a syntax error.  We avoid the syntax error here because we don't
use Python's compiler, which is the only thing that can throw
Syntax Errors.  :D

Fixes #555.

d5194f23fa Properly add yield-from, using python's real "yield from".
The yield-from that existed previously wasn't actually implementing the
full complexity of "yield from":

  http://legacy.python.org/dev/peps/pep-0380/#formal-semantics

... this includes passing along errors, and many other things.

Also removes the yield-from backport macro, since it does not seem
possible at present to conditionally build macros.

Thus, there is no longer yield-from on pre-python-3.3 systems.

Includes updated docs and tests to reflect all this.

774aad2ca8 defmain macro; handles the whole if __name__ == __main__ / main function dance
Example:

  (defmain [&rest args]
    (print "now we're having a fun time!")
    (print args))

Which outputs:

  $ hy test.hy
  now we're having a fun time!
  (['test.hy'],)

Includes documentation and tests.

b97e0258e1 Fix for #497
One would expect the form:

    > (defmacro a (&rest b) b)
    > (a 1 2)

To return a tuple object but we have no Hy model so it returns a HyList.
Not sure if this is the right thing to do.

hy/compiler.py: import only handles HySymbol and HyList, bail on others
When (import) encounters anything but a HySymbol or HyList, raise an
exception, as that is not valid in Hy. Previously, anything other than a
HySymbol or HyList was simply ignored, turning that particular import
into a no-op, which was both wrong and confusing.
