In the binary heap documentation, I read that `BinaryHeap.front()` "Returns a copy of the front of the heap". [1] Is there no function to access the front of the heap without a copy? (micro-optimization)

Answering myself here: the binary heap element type should be cheap to copy, because it is going to be copied around a lot (for the common implementation on top of an array).
