Hi everyone. I've got a few questions about the Haskell programming language.
1) what's the difference between these two code statements? I'm convinced they should be the same
type T = [Char] type CurrentValue = Char
My concern is that in the second one there are no brackets
Anyway they are actually declarations arent'they?
2) What is Maybe String?
For instance: type P = (Char, Maybe String)
Is that a function which has two arguments ?
3) What is Maybe Char ?
For instance : type D = ((Maybe Char) , Char)
It's another function having three arguments..am I right?
Thanks a lot. 777P
