Guess I really meant "object" or "type" above, not "typing.Any."
For a decade or two, my use of structs/records in Python has been
dynamically-typed and that hasn't been an issue. As the problem this PEP is
solving is orthogonal to typing improvements, it feels a bit like typing is
being coupled and pushed with it, whether wanted or not.
Not that I dislike typing mind you (appreciated on projects with large teams),
it's just as mentioned not related to the problem of class definition verbosity
or lacking functionality.
