I'll take up aliases anytime of the day... do we have any practical use cases for the NewType in production?

I don't think that I like that the following is True. If you want that to be false, what's the best way to do that? Make a @dataclass with a single field like "value", take the performance hit, and write the forwarding functions that you want to have available?
A = NewType("A", int)
B = NewType("B", int)
print(A(1) == B(1))
