No, I don't know of any that will do that. The problem I think is that parsing
a list which also includes regexp would make the optimisation process very
complex as you would have to parse the regexps and work out how to combine them
with the non-regexp elements to obtain a final optimised regexp. The parsing
would likely require a full implementation of the regexp engine.

Tim
