your factoring out could be postponned as well to that same ticket, to
keep related changes together?
I am not so sure. If I remember correctly, factoring out and using cached
method on it does provide a speed-up, and so does contribute to the
purpose of this ticket.
I'll test after lunch whether I can show the speed-up in a more or less
realistic example.
