Yep, interested in implementing it! I will put implementation time on my schedule and tell y'all when it is, for holding myself accountable -- it turns out I never do anything not on my schedule.

I still don't understand what would happen with annotations. If the decorator returns a non-function, one would expect the annotations to be in the annotations attribute of the enclosing class or module. If it returns a function, they would be in the annotations attribute of the function. And I'm talking about the runtime behavior in Python as explained in PEP484 and PEP526. I would expect these declarations to behave according to the same principles as other ways to annotate variables/functions. If there is no runtime behavior, a comment-based syntax might be more appropriate. Or have I missed something?
