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, axis=0, out=None): ... # continue with the definition of concatenate This NEP calls it an "arbitrary callable". > In `__array_ufunc__` it turns out people count on it being exactly the > `np.ufunc`. Right, I think this is good guarantee to provide. Certainly it's one that people fine useful.
