--- Comment #2 from Maxim Yegorushkin <maxim.yegorushkin at gmail dot com> 2012-07-12 14:36:52 UTC --- Fair enough. I wasn't sure whether std::pair<> should work as a range, so I went to http://gcc.gnu.org/gcc-4.7/cxx0x_status.html which refers to http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2009/n2930.html, which says that std::pair<> is a range.
