For comparison's sake, what would the above look like using class assignment? And what is the performance difference? Actually I tried but I can't implement this without module getattr so that one can just write:

from typing_extensions import allow_forward_references allow_forward_references('Vertex', 'Edge')

Maybe I am missing something, but either it is impossible in principle or highly non-trivial.
