In that case you are to be congratulated. Pay no attention to the effbot's
brusqueness, its advice is usually sound(er than mine). I suspect all the
implementation work on regular expressions has soured its outlook a little.
Of course, even if you *weren't* aware of what everyone else does, that's no
reason not to do it yourself if it works.

It's a sound general rule that if you appear to need to generate variable
names on the fly your approach may bear re-thinking.
