[boost] [smart_ptr] shared_ptr::before(), owner_less, etc.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 If I provide a patch that adds support for before() methods to boost::shared_ptr and weak_ptr, and a boost::owner_less (as described in n2637) would it be considered? I don't plan to change the semantics of boost::shared_ptr::operator<(), I just want to make it slightly easier to write code that will be portable across boost::shared_ptr and the upcoming std::shared_ptr. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFJSv/f5vihyNWuA4URAuCbAKDQc5/ufv01thvyrLUScX2GpiXMZACgkzII +6c/b6ZJ9e5oee7O9DWxI6Q= =Ggbl -----END PGP SIGNATURE-----
