My goal is to provide the scaffolding. I'm focused on getting Lexicon and PostingList right, so that you can use or abuse them as you wish. 
I¢m trying to implement my RegexpTermQuery class right now. I¢m stuck on one thing. I¢d like to use the TermScorer, so that it will be scored the same way as a single term. But looking at TermWeight, I see that $plist->;make_scorer is called inside sub scorer. I can¢t call that method on a posting list because I don¢t have just one. Am I using the right approach? Or should I be subclassing Scorer? If that is the case, what methods should I override? (I¢m still not sure exactly what the scorer is doing.)
I suppose the answers to these questions are precisely what you are working on.
Anyway, the attached patch shows what I¢ve been trying to do so far (completely untested).
