Probably so, I was just scratching an itch that I had.
My target was to make the decisions as clear as possible.
What I started from is "you only need to do work when
the next thing comes up or another entry is added."

That was the core I was going after, and I just had the None
in there so my tests could stop gracefully (in fact I printed
the leftover queue when I was testing).
