sure, but:
In [18]: sum([Decimal(1) / Decimal(3)] * 3) == Decimal(1)
Out[18]: False
Which is just as bad -- not as "confusing" to
If these examples were possible (I wouldn't say they are smart designs)
they would lead to recursion errors.
Limitations on MRO are good, they force to keep a quite simple structure.

I'm not so sure about that. I would agree that it's a gobelin, just as

My personal preference for adding units to python would be to make
instances of all numeric classes subscriptable, with the implementation
being roughly equivalent to:

Absolutely!
There is talk about "the Application" as though that's one thing, but
Python applications these days can be quite large collections of third
