Re: [Haskell-cafe] Overloading functions based on arguments?

class Foobar a b where foobar :: a -> b -> Int instance Foobar String Int where ... instance Foobar Int String where ... 2009/2/13 Daniel Kraft :

Hi,

I just came across a problem like this: Suppose I've got two related functions that do similar things, and I want to call them the same... Like in:

foobar :: String -> Int -> Int foobar :: Int -> String -> Int

(Bad example, but I hope you got the point.)

Is this kind of overloading (instead of the polymorphism based overloading) possible in Haskell? Namely to have two functions with the same name but different signatures so they could be distinguished by a call's parameters? I fear not... So I guess I have to name the functions differently, right?

Thanks, Daniel
