Ticket #12224, comment 12

-                      v2
+                      v3
+(bis). Continuing point above (testing doctests in the clean sage-main branch of sage-5.6.rc0 to see how the old behavior is changed). For now, I tested only {{{sage/combinat}}} folder. All tests pass on many of them. I get errors on 28 files and time out on 3 files. See below for the list of files.
+Below, I put some samples of failing doctests that will break my code and code of other users. These must be fixed. I can't see an argument for removing a working method from Sage...

+I don't agree with the new printing of WordMorphism. We changed it and had a discussion recently in #13677. Why should we change it again? Anyway, this discussion is independant of this ticket. I suggest this is not changed by this ticket and is discussed elsewhere.
