@philnik777 Do you remember why you added the `__is_callable` checks in the first place? The Standard isn't all that clear about what the requirements are for classic algorithms, so I think removing these checks would also be a viable path forward. I seem to remember there was a good reason for adding those, so I'm reluctant to do it without remembering the context.
