The ""non-overloaded version of the provided function" is entirely
hypothetical at this point.
If we use a decorator to implement overloads, it would be the undecorated
function, e.g., the original definition of concatenate here:
@overload_for_array_function(['arrays', 'out'])def concatenate(arrays,
... # continue with the definition of concatenate
This NEP calls it an "arbitrary callable".

Right, I think this is good guarantee to provide. Certainly it's one that
people fine useful.
