As a C++ programmer (which I'm sure undermines my argument before you've even read it...), this feels 'backwards' to me. Although I am no purist, the 'else' typically implies failure of a previous explicit condition, yet in this case, it's executed by default, when the previous clause was successfully executed. It would seem more natural if the else clause was triggered by 'bar' being empty, or even if the loop was explicitly broken out of, though I'm sure that would make the construct much less useful. -- Ben Sizer -- http://mail.python.org/mailman/listinfo/python-list
