Well the second one will soon be possible. The new regexp.erl I will be
releasing soon (real soon now) will contain a function which builds a
struture representing the regexp (a DFA for it). Just for you Joe. :-)
With this someone (me) could write a parse_transform which transforms
calls to regexp into speocialised local functions for matching regexps.
