Thanks, but I want to generate more than just numbers. I'll remember it if
I ever have any monte carlo work to do.

For now all I really need are dates, numeric strings, and alphanumeric
strings. For unit testing the code it would be nice to generate other
things, like objects, or graphs of objects.

How many people out there are doing randomized testing? Are you
generating test data with random.py and bare code, or have you
written libraries to help you define test data generators?
Or are tree structured data and randomized unit testing things
people only do in Haskell-land?
