This still technically reduces the generality of the given function since you are specifying that each function cannot have multiple overloads.

let f be a overload set matching the signatures {a -> b, i -> j} let g be a overload set matching the signatures {b -> c, j -> k}

compose(g, f) could be given a to return c or i to return k

My point was that we are almost never hurt by that reduction.

Haskell has type classes, and if we restrict ourselves to local type inference it's fairly easy to have C++ style overloads without even that. So no, I'm not specifying such a thing.
