Sure. Just tell me how else to detect const rvalues in standard C++98.
Implementation of BOOST_FOREACH seems, large, quirky, and to contain quite a few limitations. With Boost.Typeof or decltype, I can write a robust implementation in a couple of lines that is also likely to yield better code. With compilers evolving, we could make the implementation of BOOST_FOREACH evolve too. It would also be nice to strip extra parentheses on compilers that are capable of it, add BOOST_FOREACH_AUTO variants, and be able to leverage native foreach-support where available. I've already had a variant of BOOST_FOREACH that does that in my code for years. Legacy compatibility is nice, but a tool that allows to make the best of ranges on today's compilers is very important too.
