can someone from python-dev give some background of why that's the way it is?
It's because, with new-style classes, a class is also an instance (of class "type" or a subclass thereof). So without that rule, it would be ambiguous whether a dunder method applied to instances of a class or to the class itself. > and if maybe it's something which python-dev would consider worth
changing in the future -- not sure how much could break because of that though
Something fairly fundamental that would break is classs instantiation! You instantiate a class by calling it, so if a(x) were implemented as a.__call__(x), and class C had a __call__ method, then C() would invoke that method instead of instantiating C. -- Greg -- https://mail.python.org/mailman/listinfo/python-list
