For the THIRD time, I'll post my example:

    this() { /* load texture... */ }

will this be called?
}

Now, does this really seem like a realistic use case to you?

using(Texture tex = new Texture2D) {
    // ...
}


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.
