Comment(by SimonKing):
With my patch, applied on top of #11900, I get
{{{
sage -t devel/sage-main/sage/structure/parent.pyx # 2 doctests
failed
sage -t devel/sage-main/sage/structure/category_object.pyx # 2
doctests failed

sage -t devel/sage-main/sage/structure/parent_base.pyx # 2

}}}
At least some of the errors are like
{{{
sage: n = 5; Hom(n,7)
Exception raised:

and I really don't see why this should be considered a bug.
