Hi all, Thanks to John Maddok test of Boost.Bimap we discovered that some compilers (VS7.1 for example) may have a hard time recognizing between the "bimap" namespace and the "bimap" class if you try to compile the following code: using namespace boost::bimap; using namespace boost; typedef bimap<int, double> bm_type; If you switch the using statements this problem is gone in VS7.1 but persist in VS8 The following code compiles in VS7.1 using namespace boost; using namespace boost::bimap; typedef bimap<int, double> bm_type; You can use the container with the full namespace path in order to solve this problem: using namespace boost; using namespace boost::bimap; typedef ::boost::bimap::bimap<int, double> bm_type; Is this a problem that can be solved with a warning in the docs? Do you think it may be better to rename the "bimap" class to something else like "bidirectional_map"? Ideas are welcome Regards Matias
