And the call to `bin' be lifted into the Num class I suspect... leading to raw binary literals, using overloaded literal syntax. So I guess we do have binary literals then. -- Don _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
