Re: [Boost-users] Cannot use Boost.Croutines with range based for

As per DR1442 (for C++11), the rule of range-based-for has been changed. ( http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#1442 ) The new rule does not add namespace `std` as an associated namespace. So `begin` and `end` should be defined as either - member functions, or - as free functions in the enclosing namespaces (e.g. `boost::coroutines`). Recent gcc and clang implemented the new rule.
