[boost] boost exception to_string()

Hi, Is to_string() here supposed to match to_string() in boost\exception\to_string.hpp? class shared_array2 : public boost::iterator_range {}; typedef shared_array2<unsigned char> shared_data; to_string(shared_data()); I really didn't expect this to_string() to be found here.. is it a feature or is it a bug? -- Olaf
