If I use isSpace from the hugs interpretor, it works.

If I use isSpace from a test.hs file I get the error message: Undefined variable "isSpace"

From ghc I get the error message: Variable not in scope: "isSpace"

What is wrong?

Hugs automatically imports a few extra things as well as the standard prelude. Try adding the line import Data.Char to your module.
