Please provide reduced examples.

This fails:

class C
{
     int[] a;
     alias BH = BinaryHeap!(int[], (x, y) => (x+a < y));
}

This works:

class C
{
     int[] a;

     void foo() {
         alias BH = BinaryHeap!(int[], (x, y) => (x+a < y));
     }
}

But will create an instance of BinaryHeap per member function.

Dunno.
