This is what I have been referring to in my earlier comment. 
These utilities provide RAII experience very similar to one in 
C++ and work pretty good if you stick to certain style of 
programming. But they are implemented by using struct wrappers 
and all polymorphic traits are lost.

C++ does not have this strong distinction between structs and 
classes resulting in a bit more flexible RAII application. 
Writing applications in C++ style is certainly possible but may 
require some rather advanced knowledge of what can and what can't 
be done. @nogc helps here a lot.
