I think this makes it over-complicated. It is much simpler, more explicit,
and more consistent to have two properties here, one that only deals with a
string, and a second that only deals with a text object. Then you can do
something like (where titletext returns the text object):
ax.titletext.fontdict
That way we automatically get what you want without any additional work or
fancy tricks in a much cleaner, more explicit, and more predictable manner.
