> No, you just hover the function and get the help() out of it in most framework and libs. Again, if your code is mainly using a well define, documented and popular framework/lib/api, that's not a big deal. And it certainly doesn't require YOU to add types.

If the help or comments tell you the types of arguments and return values, that is just static typing in the form of comments. Even more verbose than language level type annotations, yet much harder to parse for editors/IDEs/linters.
