What's TOTALLY COMPELLING about Ruby over Python?

On Mon, 18 Aug 2003 16:22:01 -0400, rumours say that "John Roth"
<newsgroups at jhrothjr.com> might have written:

You can do similar things in Python, just wrap your collection in a
class.  Check this module:

http://www.sil-tec.gr/~tzot/python/predicates.py

See the test cases after the line
if __name__ == "main":

Does this work for you?  Esp. the do method.

PS I don't believe that the my final test labeled "Tricky" works, but
RSN I'm going to work on it :)
