Unable to use BinaryHeap container with Git HEAD. Works with dmd-2.070
Reduced code follows:

// -----------------------------
import std.container: BinaryHeap;

class Foo {
  int[] bar;
  alias BinaryHeap!(int[]) Heap;
  Heap frop;

  this() {
    bar ~= 0;
    frop = bar;
  }
}

void main() {
  new Foo();
}
