Hey Andrew, Just for reference, you do not need these lines as they are in the Tableau code so you can call Tableau(...) directly without having to explicitly create the parent object.
@staticmethod def __classcall_private__(cls, elt): return MyParent().element_class(MyParent(), elt) Although considering that the metaclass has not been set to the classcall metaclass, it should not be called.
