There's a problem with genexp's that I think really needs to get fixed. See http://python.org/sf/1167751 the details are below. This code:

>>> foo(a = i for i in range(10)) I agree with the bug report that the code should either raise a SyntaxError or do the right thing.

The change to Grammar/Grammar below seems to fix the problem and all the tests pass. Can anyone comment on whether this fix is correct/appropriate? Is there a better way to fix the problem?

-argument: [test '='] test [gen_for] # Really [keyword '='] test +argument: test [gen_for] | test '=' test ['(' gen_for ')'] # Really [keyword '='] test
