What are inline namespaces for?

http://stackoverflow.com/questions/11016220/what-are-inline-namespaces-for

a library versioning feature akin to symbol versioning but implemented purely at the C 11 level ie. cross platform instead of.. namespaces in between too . As an example consider the STL implementation of vector . If we had inline namespaces from the beginning.. #endif namespace pre_cxx_1997 template class T __vector_impl implementation class template class T e.g. w o allocator argument..
