Actually, someone recently pointed out to me
(Gavin I think) that for/in is equivalent to
each, but he had wandered away from that since
he often needed each_with_index or something
similar.

So, then. How does Python's example work when
you need the index also? Oh, it can be done,
all right. Same as in Fortran.

For that matter, how do you do each_byte in
Python, to iterate a byte at a time?

This is not a flame. I don't know Python, and
I don't participate in language wars. But the
more I learn about Python, the less impressed
I am. 

I certainly see no compelling reason for me to
switch from Ruby to Python. On the other hand,
it doesn't surprise me that they feel the same
way.
