Ralf,
Was you question concerning the specific syntax in your example?
In Axiom I would have written it this way:
(1) -> Z:=Integer
(1) Integer
Type: Type
(2) -> f(x:Z):Z->Z == (y:Z):Z +-> x+y
Function declaration f : Integer -> (Integer -> Integer) has been
added to workspace.
Type: Void
(3) -> g := f 2
Compiling function f with type Integer -> (Integer -> Integer)
(3) theMap(#<FUNCTION (LAMBDA (#:G720 |envArg|)) {BA3B6F5}>,303)
Type: (Integer -> Integer)
(4) -> g 3
(4) 5
Type: PositiveInteger
Regards,
Bill Page.
