Re: [boost] [foreach] Request for auto type deduction

Therefore, I would like to request a new tool in Boost.Foreach that would emulate the above construct, and would look something like:

BOOST_FOREACH_AUTO( const& x, collection ) {...}

I do not anticipate any technical difficulties with implementing this, as it can already be achiever with a verbose:

BOOST_FOREACH( BOOST_TYPEOF( boost::begin(collection) ) const& x, collection ) {..}

Actually, I think it has the potential of being more efficient than BOOST_FOREACH, which uses tricks that have some overhead on certain compilers. So it should not be implemented in terms of BOOST_FOREACH.
