Why isn't there any special method for __max__ in python?

As the title asks. Python has a lot of special methods, __add__, __len__, __contains__ et c. Why is there no __max__ method that is called when doing max? Example code:

class A:
    def __max__():

        return 5

a = A()
max(a)

It seems like range() and other constructs could benefit from this. Am I missing some other effective way to do max?¨

Addendum 1:
As a trivial example, max(range(1000000000)) takes a long time to run.
