Comment (by vbraun):
And you need some way to circumvent the enforced argument normalization
for internal use where you know that the arguments don't have to be
normalized. In terms of complexity / lines of code, I think its pretty
much a draw. Which is to say, you end up using a lot of complicated
machinery for no real advantage. And it gets even more complicated if you
start deriving the class. And it breaks the symmetry between different
implementations. If I had seen a real advantage with the `__classcall__`
mechanism then I would have used it myself.
