The last two commits from (Apr 9) on https://github.com/ghc/packages-template-haskell/commits/master/Language/Has... removed a helper to construct applied type class constraints (`classP`). Some packages (notably `llvm-general-pure`) though, depend on it. Can we add back something like this: {{{ classP :: Name -> [Q Type] -> Q Pred classP cla tys = do tysl <- sequence tys return (foldl' AppT (ConT cla) tysl) }}} and export it again? Or is there such a helper with a different name already? Cheers, Gabor
