#3643: Auto type deduction in 'foreach'
 Reporter: akrzemi1@… | Owner: eric_niebler
     Type: Feature Requests | Status: new
Milestone: Boost 1.42.0 | Component: foreach
  Version: Boost 1.41.0 | Severity: Problem
 Keywords: |
 I would like to request a new tool in Boost.Foreach that
 would emulate the following C++0x construct:

   for( auto const& x : collection ) { ... }

 It would look something like:

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

 To prove it is doable I enclose the following suboptimal implementation as
 a proof of concept. It was already pointed out that the faster
 implementation is possible.

     BOOST_TYPEOF( *boost::begin(CONT) ) INIT, \
     CONT \
