#5820: [with patch, needs review] implement comparison of ring coercion
morphisms
------------------------+---------------------------------------------------
Reporter: AlexGhitza | Owner: AlexGhitza
Type: defect | Status: assigned
Priority: major | Milestone: sage-3.4.2
Component: algebra | Keywords: ring coercion morphism comparison loads
dumps
------------------------+---------------------------------------------------
Changes (by AlexGhitza):
* keywords: morphism ring comparison loads dumps => ring coercion
morphism comparison loads dumps
* owner: tbd => AlexGhitza
* status: new => assigned
* milestone: sage-4.0 => sage-3.4.2
Comment:
This is actually a problem with ring coercion morphisms, namely that they
don't have a comparison method defined.
The attached patch does this and adds doctests (including {{{f ==
loads(dumps(f))}}}).
