I agree. I think that clone_ptr is designed for a rather small niche, and I can't see myself ever needing it ... but that doesn't mean it couldn't be useful to somebody.

The general idea of a clone_ptr fills a very important niche, where the compiler firewall idiom is used to limit header dependencies for copy constructible objects. Apparently that's very common -- but I have never needed it ;-) -- Dave Abrahams Boost Consulting www.boost-consulting.com
