Um... that's pretty straightforward no? Exactly how you describe:


of course it requires a regular expression matcher that supports
lookahead, but those in most modern proggraming languaes do so.

I'm not sure that using tokens in the way you describe is a good
idea in the specific case of wiki markup -- it surely makes a lot
of things more complicated.
