Interestingly enough, I'd already swapped out the list comprehensions
for a single for loop. :^)

Some respondants seemed confused about what I was trying to do... I'm
communicating with a C program that generates datagrams from a C
structure. Many of the datagrams have, for the last two fields,
"unisigned int datasize; char data[]". I wanted a convenient way of
extracting the fields of known size, and the data blob at the end.

If others are interested in the class I've built, I can make it
available (maybe through the Cookbook web site) when it's a little
more mature.

Again, thanks for all the pointers. Although the language itself is
the first reason, the community is a close second for why I love
programming in Python.
