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.
