An interesting side note, and one that could be granted to the OP, is

for in-place assignment operators like += (by defining a method
__iadd__).  This is how numpy's values accomplish their mutability.

Maybe it's time we added a new acronym to this group's ongoing
discussions: PDWTW, or "Python doesn't work that way".
