[Python-ideas] unittest: assertEqual(a, b, msg): Show diff AND msg

Up to now assertEqual(a, b, msg) outputs only the msg, not the diff.

I know that setting longMessage to True shows the diff and the msg[1]

I think the sane default is to show the diff and the message for assertEqual().

What do you think?
