I have a follow-up to my original message regarding a typeless emulated rvalue reference. I was disappointed in the lack of feedback (other than Dave) on the original message, which might mean that those who took the time to parse the message didn't think it was worth pursuing;
Yes sure. Not everyone is able to see as quickly as him when there is something really valuable ;-)
It's probably more likely that not everyone has as much time as Dave does ;) What about renaming genrv to any_rv?
Yeah, that's probably a better name.
Have you already thought about how this enhanced emulation could be used in a portable way on C++98 and C++0x compilers?
No, I haven't :( At this point, the easiest way to write portable code seems to be to do an ugly "#ifndef BOOST_NO_RVALUE_REFERENCES / #else / #endif" dance :( Which I would expect would make it largely inaccessible to general users, mostly relegating this technique to libraries that want to provide a more performance-friendly interface. - Jeff
