The same is true in OpenAxiom -- I would suspect in FriCAS too.

Since this is a discussion of Monad and not categories as parameters
as such, consider instead
Monad(A: SetCategory, M: SetCategory - SetCategory): Category == with {
unit: A - M A;
mult: M M A - M A;
}

2) If yes, is it useful? How to use it?
3) Why doesn't this compile? (Discussion of function versus functor.)
4) Is there another way to write it that does compile and that would
be a useful way to represent a monad-like construction
