Description
The following currently results in an error:
sage: class P(Parent): ....: def __init__(self): ....: Parent.__init__(self, category=Sets()) ....: def _coerce_map_from_(self, A): ....: if A == ZZ: ....: return lambda x: self.element_class(self, x) ....: return False ....: Element = ElementWrapper ....: sage: X = P() sage: X.has_coerce_map_from(ZZ)
the reason is CallableConvertMap
is not being given the correct input data.
