Just to give my $0.02 as an experienced Python developer who has not yet even tried to get into typing: the given examples barely look like Python to me, and at first glance I have no idea what they do. That said, they also look more legible than the “before” examples in the PEP. I suppose that means that if this is a significant need in the typing world the proposed solution is probably fine, but I’m not looking forward to having to dive into some thoroughly-typed codebase to try to make sense of what it’s doing.
