    This bytecode distinguishes two cases: if ``STACK[-1]`` has a method with the
    correct name, the bytecode pushes the unbound method and ``STACK[-1]``.
    ``STACK[-1]`` will be used as the first argument (``self``) by :opcode:`CALL`
    or :opcode:`CALL_KW` when calling the unbound method.
    Otherwise, ``NULL`` and the object returned by
    the attribute lookup are pushed.
