Assuming we move the Parsec 'many' implementation into the Alternative class definition, this should have no/little impact on performance for all the combinators mentioned by Stephen.

I can't speak for Parsec, but I certainly have a local definition of "many" in attoparsec, because the Alternative version isn't inlined. Makes a biggish difference to performance, though I do not recall the magnitude (2x?).
