Thanks, yes, that did work. However now when trying to insert
nodes I get this error: Cannot grow a heap created over a range.
I This is what I have:
Node[] a;
auto b = BinaryHeap!(Node[], "a.fScore > b.fScore")(a);
Node test, test2;
test2.fScore = 9;
test.fScore = 10;
b.insert( test );
I also tried this:
Node[2500] a;
auto b = BinaryHeap!(Node[], "a.fScore > b.fScore")(a);
Node test, test2;
test2.fScore = 9;
test.fScore = 10;
b.insert( test );
It gives the same error.
I also tried this:
Node[2500] a;
auto b = BinaryHeap!(Array!Node, "a.fScore > b.fScore")(a);
Node test, test2;
test2.fScore = 9;
test.fScore = 10;
b.insert( test );
Error 1 Error: this._store()[this._length()] is not an
lvalue C:\DLang\dmd2\src\phobos\std\container.d 2676
How exactly would I grow this heap? or How would I give it enough
room so that I don't need to make it larger?

I'm still having troubles with the min-heap.

That is an API design issue. This should work:
auto b = BinaryHeap!(Node[], "a.fScore > b.fScore")(a);
