Re: [Jython-users] pyparsing

[Charlie G. <cha...@gm...>]

http://jython.org/bugs/1230674 explains that from __future__ doesn't
work from the interpreter.  We've got a patch for it, so it should
fixed in 2.2 but it hasn't been applied yet.  You should be able to
use generators from a .py file without problems now.
