Regex Thoughts

After skimming Wall's latest Apocalypse on regexes , I think the next version of the CLAWK regex engine will move towards supporting something close to this, although probably as a separate syntax. Several of the features he's talking about are supported by the intermediate representation and the backend compilers, but there's no good way to add them to the surface syntax and remain compatible with AWK regexes.

Besides the changes to the surface parsers, I will also be putting in support for a sexpr surface syntax.
