For that purpose we'll need something like
scoped_lock(mutex&, nolock_t);
I'm increasingly liking this syntax, by the way; thanks for suggesting it.
I don't know the original intention, but my assumption about the "bool" parameter was that it was intended to be used to check (run-time) conditions that might eliminate the need for locking under certain circumstances, e.g., bool foo(bool threadsafe) { mutex::scoped_lock l(m, !threadsafe); } Using types such as nolock_t would prevent such a usage.
