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)Thanks, Johan[1] https://dlang.org/phobos/std_container_binaryheap.html#.BinaryHeap.front
What does
foreach(ref e; bh)
{
//...
}
do?
