Yes, I realize that this (or the += approach) was overdoing it. Separating
the stuff in two different properties is probably more the way to go (at
least, it's less crazy).
Even the ax.title += (string, options) approach has the problem that this
would imply ax.title (in the sense of ax.__dict__["title"].__get__(ax))
cannot be a string anymore, so this would involve some wrapper object. Ugh.
