For loop comprehensions

[Benjamin S Wolf]

It occurred to me as I was writing a for loop that I would like to
write it in generator comprehension syntax, eg.

  for a in b if c:

rather than using one of the more verbose but allowable syntaxes:

  for a in (x for x in b if c):

  for a in b:
    if not c: continue

Python 3.1 does not support "for comprehensions", and a few cursory
searches of PEPs and this list don't turn up anything. I like the idea
enough to suggest it though I'm unfamiliar with the PEP/feature
request process (PEP 1 pointed me here). What do other people think?
