It does, entirely. I usually translate it to D this way:

{
     Texture tex = new Texture2D;
     scope(exit) tex.destroy;
     // ...
}

Of course, nothing protects you from passing the reference 
outside the scope and having a dangling ref after the scope ends, 
so it's by no means safe, but the destruction is deterministic.
