The scoped_lock assignment operators make me a bit nervous. For
instance, you don't specify what this should do:
Mutex mut;
scoped_lock< Mutex > l1( mut ); // lock once
scoped_lock< Mutex > l2( mut ); // lock twice (recursive)
l1 = move(l2); // ???
If I had to guess, I suppose this would have the effect of simply
unlocking l2. Or should it throw? I would prefer the former if I had to
choose, but the specification should be clear on this point.
Oh, and thanks for your work on the spec Howard. :-)
