This won't work. Try to compile this with Comeau online:
You'll get:

Non-copyable types can't be initialized this way. The code I posted earlier worked around this problem by enabling just enough move semantics to allow a lock to be returned from a function, but nothing else. The lock is still non-copyable.
*pouts* Well, fooey. Glad you got it working, though, I missed that post. My point still stands, I think the movable lock should be a separate type from the scoped lock, even if we implement minimal move semantics to support assignment initialziation.
