User data type with operator contructors only
Hello all, my question probably comes from not reading manual properly. But, why is it not possible to have something like: infixr 5 :> data Stack a = a :> (Stack a) | :|| And if yes, how can I do that? I know that lists are a hack in Haskell, but anyway. Having: infixr 5 :> data Stack a = a :> (Stack a) | Bottom is not what I would like to have. :-( Thanks for any reference to/or explanation, Dusan

Hmm, I see, ghci works, but hugs not. That was my problem. Sorry for asking. I've thought this would work in both. :-( Dusan
