I wrote the below code

    global called
    called = False
    class MyType(type, ):
        def __new__(self):
            pass
        def __clrtype__(self):
            global called
            called = True
            return super(MyType, self).__clrtype__()
    try:
        class X(object, ):
            __metaclass__ = MyType
        Fail('type.__new__    signature    is    wrong')
    except TypeError as e:
        AreEqual(e.message, '__new__()    takes    exactly    1    argument    (4    given)')
    finally:
        AreEqual(called, False)

What's a good function header?
