Looping over a list question

[stephen at theboulets.net]

I found myself writing:

for f in [i for i in datafiles if '.txt' in i]:
    print 'Processing datafile %s' % f

but I was wishing that I could have instead written:

for f in in datafiles if '.txt' in f:
    print 'Processing datafile %s' % f

Has there ever been a proposal for this? Just wondering ...
