I think adding type hints to docstrings is a fine thing to do if any given
developer wants to. I don't think we should have a policy requiring it or
Note that the PEP states these type hints are for static analysis not
runtime type checking. Besides the pep's stance on that, I don't think
CPython supports runtime type checking based on these types. Since vim and
PyCharm support the static analysis already, if it were to be used, we
would derive the value it creates right away.
