used by _Black_ can be viewed as a strict subset of PEP 8.

[YAPF](https://github.com/google/yapf)'s block comments to the same effect, as a
courtesy for straddling code.
_Black_ enforces the above rules. There are additional guidelines for formatting `.pyi`
file that are not enforced yet but might be in a future version of the formatter:
-- all function bodies should be empty (contain `...` instead of the body);
-- do not use docstrings;
- prefer `...` over `pass`;
-- for arguments with a default, use `...` instead of the actual default;
- avoid using string literals in type annotations, stub files support forward references
natively (like Python 3.7 code with `from __future__ import annotations`);
- use variable annotations instead of type comments, even for stubs that target older
- versions of Python;
-- for arguments that default to `None`, use `Optional[]` explicitly;
-- use `float` instead of `Union[int, float]`.
