Good to know. What is the criteria for binding then? Does it check if its type is `vanilla` function? If yes, is there any way to simulate it for arbitrary object?

I have tried inheriting from function type, but not allowed.

Yes, I have tried that. This works well. But maybe will be useful for another case.

Currently, the focus is decorators that can be used on arbitrary methods. Needing to inherit and add metaclasses whenever I want to decorate is not an option.

I think I will continue with descriptor approach and am slowly finding route to get where I need to, but still exploring options.
