[smart_ptr] comparison of intrusive_ptr objects
Does anybody know why intrusive_ptr has ==, != and < operators, but the rest ones are missing (i.e. >, <=, >=)? It makes hard to use intrusive_ptr in generic code.

Can't you use std::relops to get those? -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkrCBW0ACgkQ5vihyNWuA4WT7gCgvqs6h/nOnh2i+kaegRgSv548 A8gAn06BOTpXpQy28QWOfLubZHCCf0KG =KJNj -----END PGP SIGNATURE-----

Generally, the convention is for generic code to use only <, ==, and !=. In Christ, Steven Watanabe

Search for the subject line: Please don't define a fake"operator<"just for ordered containers" in the boost archives. ie starting at or around http://lists.boost.org/Archives/boost/2006/07/107267.php Make sure to continue into the next month, and the next,... Happy reading. Tony
