Bug 6959 – std.container's BinaryHeap doesn't work with Array!(T)

The documentation of BinaryHeap in std.container says that: "If Store is a range, the BinaryHeap cannot grow beyond the size of that range. If Store is a container that supports insertBack, the BinaryHeap may grow by adding elements to the container." But the Array!(T) container, which does have a insertBack() method, can't be used with a BinaryHeap, as the following code: import std.container; void main() { auto array = Array!(int)(); auto heap = heapify(array); //auto heap = BinaryHeap!(Array!(int))(array); // gives same error } Gives the following compilation error: \phobos\std\container.d(2660): Error: this._store()[this._length()] is not an lvalue This happens to make growable BinaryHeaps impossible using only Phobos containers.
