​As previously stated this builtin is the only one not doing the right
thing. If you think otherwise, please provide proof. I provided plenty of
supporting examples.

Your "working around" is basically saying "don't use​ callable or don't
solve your problem". Not an option.

Let me restate the problem: I want to implement a "proxy that resolves the
target at a later time". That means I can't juggle classes ahead of time
(no `resolve_proxy` or whatever) and I can't tell users "don't use
callable" (what's the point of having a proxy then?).
