If you don't pass it to both the constructor and the preparer then
all metaclasses which take keyword arguments must have a __prepare__
function whether they have custom local storage or not. This seems
to be non-obvious and it also unnecessarily conflates the issues of
custom locals storage and passing arguments to metaclasses.
