Understood, I was concerned the process could take longer. The code itself
isn't too complicated, but I'm not sure how much time it'll take to reach
consensus on the interface. On the other hand, it may go quickly if we model it
after the ring API -- my current thinking -- which folks seem to generally like.
Anyway, I'll rework this into a standalone stack library.
