Summary: Argument genexp corner case

Initial Comment:
The following raises an unexpected exception; I would
expect it to either work or raise a SyntaxError.  It
seems that the grammar parses it, but the compiler does
not do the right thing.

>>> def foo(a): pass

>>> foo(a = i for i in range(10))

Traceback (most recent call last):
  File "<stdin>", line 1, in ?
NameError: name 'i' is not defined

foo(a = (i for i in range(10)) works.
