This is a subtle tweak: The __new__ method is currently causing classmethod warnings (e.g., ARG003). However, it should actually be causing staticmethod warnings (e.g., ARG004).

class A:
    def __new__(cls, unused_static_method_arguments):
        return 42


A.__new__(A, 1)  # It works!!  If __new__ is treated as a class method, it should be `A.__new__(1)`

NOTE: According to the official Python documentation, the __new__ method is a staticmethod that takes the class itself (cls) as its first argument.

Reference

Called to create a new instance of class cls. __new__() is a static method (special-cased so you need not declare it as such) that takes the class of which an instance was requested as its first argument.
