I think this would be better than nothing. But it is a little verbose. And it requires you to supply the type hint. I use type hinting, but I don't want to use it every time I provide an Annotation/docstring. Maybe we could do both: establish the 2nd argument of Annotated as the docstring (and adjust the output of help() and other tools accordingly), but also provide a new "shortcut syntax" as Steven proposed: E_s : float : "the elastic modulus of steel" ... is sugar for: E_s : typing.Annotated[float, "the elastic modulus of steel"] ...and: x :: "spam" ...is sugar for: x : typing.Annotated[typing.Any, "spam"] --- Ricky.
