Replacing equals by equals usually doesn't change anything.What kind of equality do you use for getChar :: IO Char ?
The usual one: getChar = getChar. It's a pure value. If I find [getChar,getChar] in a program, I can safely replace it by let g = getChar in [g,g]. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
