> if you think about it, that's not really a reasonable thing to want to do. That RIAA lock-taker is not the kind of object that you want to move, or even copy. It actually is (at least re: moving). Tying lock acquisition to object lifetime is a Good Thing (TM), and if you wanted to extend or shrink the lifetime of that lock you should be able to do that by moving the RAII object, the same as how you could do it with a shared_ptr or whatever.
