Thank you for your answ
Oh, the pyparsing rendition of your initial pat expression would be
something like:
import pyparsing as pp
pat = pp.Combine( pp.oneOf("$ 0x 0X") + pp.Word(pp.hexnums,max=8) )
Combine is needed to ensure that the leading $, 0x, or 0X is
immediately followed by 1-8 (and no more than 8) hex digits.

Well, I fear this may end up being another of those "easier to
reinvent" wheels. All of your issues with RE's are the same ones I had
with lex/yacc (and re's too) when I wrote pyparsing.
Any chance for convergence here?
(BTW, there is nothing inherently wrong with "reinventing whee
