What is this?

[rchen152]

The syntax for positional-only parameters is new in 3.8, so before that, you would use a double-underscore-prefix naming convention to indicate positional-only parameters (https://typing.python.org/en/latest/spec/historical.html#positional-only-parameters). Typeshed switched over to the dedicated syntax a while back, so I think it matters now only for third-party libraries that might still be using the old convention.
