Thanks for working on this. I tried working on it for a while, but I got stuck on trying to understand the code. I think this would be one of the most valuable features of basedpyright.

i ran into a difficult to solve edge case that led to me abandoning this change for now (see the failing test case) but i may give it another go in the future
