Calling ``m(arg-1, +arg-2, ..., arg-n)`` is completely equivalent to calling ``m.__func__( +m.__self__, arg-1, arg-2, ..., arg-n)``. Class instance methods are either *bound* or *unbound*, referring to whether the method was accessed through an instance or a class, respectively. When a method -is unbound, its ``im_self`` attribute will be ``None`` and if called, an +is unbound, its ``__self__`` attribute will be ``None`` and if called, an explicit ``self`` object must be passed as the first argument. In this case, ``self`` must be an instance of the unbound method's class (or a subclass of that class), otherwise a :exc:`TypeError` is raised. Like function objects, methods objects support getting arbitrary attributes. However, since method attributes are actually stored on the underlying function -object (``meth.im_func``), setting method attributes on either bound or unbound +object (``meth.__func__``), setting method attributes on either bound or unbound methods is disallowed. Attempting to set a method attribute results in a :exc:`TypeError` being raised.
