Re: [Boost-users] [boost-users][bind, signal] binding a weak_ptr?

Oh, I see that thread_safe_signals already does what I need - one can
safely bind a regular pointer instead of shared_ptr (by the way, is it
safe to do this if the object already inherits from
enable_shared_from_this?).
Is it planned to be released as a part of 1.36?
