Thanks everyone for your comments and patience. There's a new spec up at:

I've tried to incorporate those comments I've agreed with, and explain my disagreements below. Further discussion would be much appreciated. I feel there has been dramatic improvements in this first iteration of the spec. Thanks again!
<snip> 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. :-) -- Eric Niebler Boost Consulting www.boost-consulting.com
