Can I define a class which inherits from both Element and
UniqueRepresentation? It doesn't seem like it:
sage: from sage.structure.element import Element
sage: class A(Element, UniqueRepresentation): pass
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-2-3cd536b3d8f4> in <module>()
----> 1 class A(Element, UniqueRepresentation): pass
TypeError: Error when calling the metaclass bases
metaclass conflict: the metaclass of a derived class must be a
(non-strict) subclass of the metaclasses of all its bases
How can I work around this?
