I just stumbled upon the following hunk later in the queue, and thought we might as well fold it into this patch:
diff --git a/sage/categories/category.py b/sage/categories/category.py --- a/sage/categories/category.py +++ b/sage/categories/category.py @@ -627,8 +627,19 @@ class Category(UniqueRepresentation, Sag sage: F in Algebras False + + TESTS: + + Non category object shall be handled properly:: + + sage: [1,2] in Algebras + False """ - return any(isinstance(cat, cls) for cat in x.categories()) + try: + c = x.categories() + except AttributeError: + return False + return any(isinstance(cat, cls) for cat in c) def is_abelian(self): """
I am running the tests now. Florent: shall I reinstate the positive review if the test pass?
