[Haskell-cafe] data Bin = Zero | One

Hi

data Bin = Zero | One As suggested by someone on this list. It's a really neat idea although I'm wondering how I can apply this to my int to binary function. The Zero or One declaration is saying that Bin is a data type that can hold either a one or a zero. I tried testing this with a very simple Bin -> Bin function and the Integral values 0 and 1 but ran into difficulties. Any ideas what I'm doing wrong here? Incidentally, does the general syntax above come from the old BNF notation? Cheers, Paul
