Is this a type narrowing bug?

[robert-bn]

I'm not sure if this is intended behaviour or not:

When checking referential equality to Ellipsis (...) the narrowed type according to Pyright 1.1.379 CLI is None, rather than EllipsisType.

def example(x: object):
    if x is ...:
        reveal_type(x)  # Pylance: Type of "x" is "None"

Yes, that's a bug. Thanks for reporting it. This will be addressed in the next release.
