[issue41987] singledispatchmethod raises an error when relying on a forward declaration

[Ryan Sobol]

Ryan Sobol <hello at ryansobol.com> added the comment:

Also, I'm a bit puzzled about something from the previously mentioned Integer class and its use of __future__.annotations. 

Why is it possible to declare an Integer return type for the add() method, but only possible to declare an "Integer" forward reference for the _() method?
