[boost] Re: Lock unification [move]

I mostly agree with Bronek Kozicki. Given a movable lock, Eric Niebler's proposal:

scoped_lock try_lock( Mutex & m ); scoped_lock timed_lock( Mutex & m );

is a better try/timed interface. Heisenberg constructors must die.

I'm not sure if there are any advantages, but try_lock and timed_lock could actually be derived classes of scoped_lock in that case, using an intentionally slicing move. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
