Do you actually do this? I can think of many examples of searches I could do 
with regexps that I couldn't do with the functionality I am proposing. 
However, I can't think of any examples that I would actually use for any 
practical purpose. Since I am not going to remove or change the current 
regexp functionality all I really care about is whether there is some way I 
could extend what I am proposing to cover things that people currently do 
with regexp since regexp will not (and probably can not) get an speed boost 
but the new searching will be much faster.

Never fear, I'm only adding, not taking away :-).
