This is a split from Issue 5462 .

In code that uses the BinaryHeap I often use two lines of code like (note it
use removeFront and not popFront):

auto item = heap.front;
heap.removeFront;

So I suggest to add to BinaryHeap a handy member function pop() that does both
things:

auto item = heap.pop;

(In a dynamic array a pop() should call back+popBack, so it's a function
specialized for heaps.)
