OK, you're on.

With LaTeX, the monkey-see-monkey-do approach works pretty well,
combined with the Fred-will-fix-my-LaTeX-bugs approach. :-)

I don't know about a SIG.  Testing of what's in the core is fair game
for python-dev.  3rd party testing, ask around.

Writing a good regression test requires excellent knowledge about the
code you're testing while not touching it, so that's indeed a good way
to learn.
