Re: [Haskell-cafe] typeclass question

Well, it's a library that others might use, so I would prefer to avoid using language extensions, especially functional deps which I don't understand, and which seem to have an uncertain future.

I think there will be a storm of protest if support for this simple shape of dependencies ( ... | a -> b ) would be dropped from the major Haskell implementations. (There used to be some status page on what compiler supports what extension, anyone know the current location for that?) J.W.
