Wow, that's the same wheel I just reinvented! Works fine in my test
functions. Guess I can scrap my home-brewed functions that do the same
thing.

Yes indeed, looks very promising.
I see there are also test frameworks available at
http://en.dklab.ru/lib/dklab_pgunit/ and http://www.epictest.org/ .
This will take me a while to digest, but hopefully I'll be able to scrap, or
greatly simplify, my elaborate homemade test functions too. It's always a
joy to be able to replace my own code with somebody else's.
