Ok. I will rebase when next release is out.
Could you please help me with #23322, on which I am breaking my head right now ?

Replying to @fchapoton:

motivated by #22945

This is a very weak motivation. Please elaborate why you think that this is needed...

I would prefer to require that variable names should be strings and nothing else. Of course, in Python 3, string == unicode so you get unicode support "for free" in Python 3.
