I wrote the below code

    global called
    clr.AddReference('IronPythonTest')
    import IronPythonTest.interop.net.type.clrtype as IPT
    from IronPython.Runtime.Types import PythonType
    called = False
    class MyType(type, ):
        def __clrtype__(self):
            global called
            called = True
            return IPT.NegativeEmpty
    class X(object, ):
        __metaclass__ = MyType
    a = X()
    AreEqual(clr.GetClrType(type(a)), clr.GetClrType(IPT.NegativeEmpty))
    class MyType(type, ):
        def __clrtype__(self):
            global called
            called = True
            return IPT.NegativeNoConstructor
    class X(object, ):
        __metaclass__ = MyType
    a = X()
    AreEqual(clr.GetClrType(type(a)), clr.GetClrType(int))
