Since I needed a MinHeap anyway, I figured I would throw my version into the ring. In my case, I'm working on a toy game prototype where the simulation runs a clock that keeps track of the time in-game, and I have callbacks that I want to run at a particular game time, so the callbacks go into a priority queue and each time the simulation clock ticks up, I execute all of the callbacks that are before the new in-game time.
