I get the change and that it was necessary for range-based for loops, but this means that you now have to `#if BOOST_VERSION < …` around it. See [[http://boost.codepad.org/VE1QSmSz|this example]] (distilled from actual code). Why the ticket? Because the change hasn't been mentioned at all in the [[http://www.boost.org/users/history/version_1_56_0.html|release notes]]." Bugs assigned To Be Determined range Boost 1.56.0 Problem
