The commit message confused me briefly, until I realized v3 of this
patch came later in the series, where it modified check_keys() type
hints and added default values.
What about this:
This is a minor adjustment that lets parameters @required and
@optional take tuple arguments, in particular (). Later patches will
make use of that.
