Re: Conway's Life

I'll answer my own question; I've got a much better implementation, along with an HOpenGL-based frontend, at "http://ofb.net/~abe/hlife/hlife-0.1.tar.gz";. It uses a FiniteMap of 5x5 UArrays that are created and destroyed as needed; this gives it a good balance of size (the grid is only bounded by

QuickCheck is in de "util" package. You can load a package with the -package flag: $ ghci -package util Prelude> :browse QuickCheck class Arbitrary a where { arbitrary :: Gen a; coarbitrary :: forall b. a -> Gen b -> Gen b; } arbitrary :: forall a. (Arbitrary a) => Gen a ... Prelude>:module Q

RE: polymorphic type in state of state monad

| | > type State = Term a => [a] | | > data M a = M (State -> IO(State,a)) | | | | GHC yields a error message "Illegal polymorphic type". | | How to resolve this? I can tell you what it happening. If you have -fglasgow-exts on, the type for State is short for type State = forall a.
