OK, so does that take us back to (3), namely the accumulator style? Can you switch the style?
I think that would just bring us back to using plain old VarSets, which we have already profiled. I could of course make a VarSet flavor that has the additional interesting function and in_scope checks, though I have doubts on whether it would reveal anything new. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14880#comment:88 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
