This seems like a good idea but it's kind of strange to have three different exposed versions of nub. Would it be possible to hide them, hide the StopList typeclass and use {-# RULES #-} pragmas to use the faster versions when possible?

I don't think that using RULES pragmas is a good solution to the problem.

Why not? I thought that was the major purpose of RULES - to implement transformations that don't affect semantics. It seems silly to clutter
