#14537: Composition of morphisms
--------------------------+-------------------------------------------------
Reporter: tfeulner | Owner: nthiery
Type: defect | Status: new
Priority: major | Milestone: sage-5.10
Component: categories | Keywords: composition, morphisms

The following code leads to a TypeError
{{{
sage: F.<a> = GF(4)
sage: x = F.Hom(F).identity()
sage: z = F.hom([a])
sage: a = (z*x)
sage: x*a
}}}
The question is could these type checking be relaxed in
categories.morphism.IdentityMorphism.
