As it so happens, boost::begin and boost::end do ADL on behalf of the users -- their Standard counterparts do not, and a range-for statement is specified to make use of unqualified calls to begin and end. To substantiate my hypothesis, adding begin and end function templates in e.g. namespace boost::coroutines does appear to make the previous snippet compile, and more involved examples behave as expected. {{{#!cpp // Try adding this: namespace boost { namespace coroutines { template auto begin(coroutine& c) -> decltype(boost::begin(c)) { return boost::begin(c); } template auto end(coroutine& c) -> decltype(boost::end(c)) { return boost::end(c); } } } }}}",Bugs,closed,To Be Determined,coroutine,Boost 1.53.0,Problem,fixed,,
