[issue37835] typing.get_type_hints wrong namespace for forward-declaration of inner class

Netzeband added the comment: Thanks for your explanations. It sounds, that there is no way to fix this issue officially. Only the meta-class workaround is left, which is - as you highlight - really just a workaround. I anyway always wonder, why functions, which are methods, do not hold a

[issue37835] typing.get_type_hints wrong namespace for forward-declaration of inner class

Netzeband added the comment: I think I found a better workaround (by accident). I was debugging another issue with get_type_hints for the case that this function is used inside the __new__ method of a metaclass and with methods of the class to define. Here the same issue happens: Forward dec

Netzeband added the comment: I tried my idea with the small example code above. However it does not work like expected: (see zipped example project, attached to this comment) At the moment where the function decorator is applied to the method of the inner class, the local namespace ("locals

Netzeband added the comment: Thanks for your response. I was also thinking much about it and was not able to find a nice idea how to get this working. The problem is, that we loose the local-namespace information as soon as we leave the context of the function, where the class was defined i

[issue37835] typing.get_type_hints wrong namespace for forward-declaration of inner class

New submission from Netzeband : When evaluating the type-hints of an inner-class (a class defined inside a function scope), the forward declaration does not work correctly. In this case the typing.get_type_hints does not get the right namespace, thus the class-string specified is not found.
