I'm not sure in what case code like what Skip shared wouldn't result
in an error:
for i in range(1, 10):
for i in ['foo', 'frob', 'bob', 'bogus', 'smogus']:
do_stuff(i)
do_other_stuff(i)
do_other_stuff will probably raise a TypeError if it's expecting an
int instead of a string (and is doing something that cannot be done to
both). I'm fairly confident this will be an error in most cases and
for the people for whom it will be a false positive, it will maybe
teach them to write better loop variable names.
