[Haskell-beginners] Is there a way to hide an existing data type so that I can use my own version?

[Costello, Roger L.]

Hi Folks,

For learning purposes, I created an "Either" data type:

data Either a b = Left a | Right b
                           deriving (Show)

However, when I try to use Left (or Right), I get an error message saying that it is ambiguous whether I am using Prelude.Left or Main.Left

So I tried hiding Prelude.Either like so:

import Prelude hiding Either

But that produced an error.

Is there a way to hide the existing Either data type so that I can use my own version?
