I looked at pyparsing about a year ago for some project and realized
that it wouldn't quite do what I needed it to. Maddeningly enough, I
cannot remember exactly what the problem was, but I think that it was
some combination of lack of backtracking and insufficient control over
whitespace skipping.
Mostly off-topic, what I could *really* use is something like this
folded into the Python standard library. I cannot count the number of
times that this would have saved me 30 lines of code.
