[Haskell-cafe] Overloading functions based on arguments?

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?
