Hi all.

I want to overload the operator "^" for working instead of the following "+++" operator:

(+++) :: String -> [[String]] -> [[String]] x +++ y = [ x:e | e<-y ]

How can I overload the "^" operator?

import Prelude hiding ( (^) ) -- this is the key (^) :: String -> [[String]] -> [[String]] x ^ y = [ x:e | e<-y ] By the way, there's nothing special about Strings here: if you made the type of ^ (^) :: a -> [[a]] -> [[a]] it would work on lists of any type, including String. -Brent
