For example putStrLn's InfoTable says arity 2 Ok, expanded: String -> (State# RealWorld) -> (# State# ReadWorld, () #) But the function type is ARG_P. Which means one parameter in stack (and it's a pointer). This might be due to RealWorld getting optimised away, but it still makes function arity-field pretty useless as far as I can see. Well, useless and pretty misleading :) Thanks, --Esa _______________________________________________ Cvs-ghc mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/cvs-ghc
