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.
