I am kind of diving in here having not read much of the option< T & > stuff in this thread, but how about.. o = make_optional( &rb ); To balance the indirection of *o and o-> Also, could be compatible with pointers int * p = make_optional( &rb ); o = make_optional( p ); p = make_optional( o ); See my earlier post for an example (I used "opt" instead of "make_optional"). Hamish PS. I know, I was the one arguing against pointer interfaces a few hours ago and now I want more :-) (but not safe_bool, "!o" or "o != 0")
