Small mistake here: "Array" is a data constructor (such like "Constant")
here, *not* a reference to the Array type.
Correct is:
import Array
data Expression = Constant String | Arr (Array Int Expression)
> anExp = array (0,1)[(0, (Constant "0")),
> (1, (Constant "1"))]
And this should be
anExp = Arr $ array (0,1) [(0, (Constant "0")), (1, (Constant "1"))]
