Re: [Haskell-cafe] Extending the idea of a general Num to other types?

Snif, this is sad... :-( Oh well, maybe this gets improved in Haskell Prime ;-) Lennart Augustsson wrote:

You're right. The list syntax is only for lists in Haskell. It would be nice if the list syntax was overloaded too. You can overload numeric literals (by defining fromInteger) and string literals (by defining fromString, in 6.7). BTW, the [1..10] syntax is overloaded, you need an Enum instance.
