This code...

    match my_maybe:
        case Maybe.empty:
            print('FIRST CASE')
        case _:
            print('DEFAULT CASE')

... is roughly equivalent to this code:

    if my_maybe == Maybe.empty:
        print('FIRST CASE')
    case _:
        print('DEFAULT CASE')

I don't think this is a bug in the match/case compiler, I think it's simply a matter of how Maybe() == Maybe() evaluates. Since your __new__ code always returns the same object, Maybe() == Maybe() will return True. But by default, each Maybe() call constructs a new instance that won't be equal to any others.
