What about:
```
class MyResource

    void* handle;
    this()

        handle = create_handle();

    close()
    {
        if (handle)
            free_handle(handle)
        handle = null;
    }
    ~this()
    {
        enforce(!handle,"Resource leak");
    }
}
```



Unique!T destructor calls delete which calls ~this() not close()
RefCounted!T and scoped!T call .destroy which calls ~this() not 
close()
We really want one thing there.
