New submission from Alex Grönholm <alex.gronh...@nextday.fi>:
>>> DummyDict = TypedDict('DummyDict', {'x': int, 'y': str}, total=False)
>>> DummyDict.__required_keys__
frozenset({'x', 'y'})
This happens because the TypedDict function does not pass the "total" metaclass
argument to _TypedDictMeta() (instead passing "__total__" in the attribute
namespace) and the new code that sets __required_keys__ and __optional_keys__
only checks the metaclass argument.
