Do not allow returns with arguments in generators #20
Description
The following is accepted by the compiler, even though it is not valid in Python:
def f():
yield 1
return 1
There should be a compile error if mixing return with an argument and yield within the same function.
Update: only disallow this in Python 2 (see below).

This is invalid in Python 2 (and the existing Python 2.7.8 compiler will give you a SyntaxError for this), but valid in Python 3 due to PEP 380 http://legacy.python.org/dev/peps/pep-0380/

Okay, only disallow this in Python 2 mode?

Yeah, it's a feature and not a bug in Python 3 :)
