Re: [boost] BOOST_FOREACH slow?

During FOEACH's review, extensive performance tests showed FOREACH was only about 5% slower than the hand-coded equivalent on average.

Why not make FOREACH as fast as hand-coded equivalents when it is possible? With decltype, typeof, or the MSVC hack it shouldn't be a problem. Also some compilers have native support for foreach-like loops.
