   Other cases from a quick audit:

   • typing._proto_hook eagerly evaluates annotations. Looks like this could trigger on code like isinstance(X, SomeProtocol) where X has deferred annotations. It doesn't need to know the value of the annotations, only what keys exist.
   • inspect._signature_is_functionlike looks for the presence of annotations to decide that something is functionlike. Maybe it should look for __annotate__ instead?
   • pydoc in two places looks for the presence of annotations for something with lambdas that I haven't fully deciphered
   • reprlib.recursive_repr creates a wrapper function that inherits __annotations__. It should probably use __annotate__ instead.
