Not that I'm arguing with classification of this change as a major one, 
but I wouldn't consider it a breaking one as I don't think adding any 
symbols to a library namespace (except where explicitly allowed by 
contract) is a valid use of the library. This is the same stance as the 
standard C++ library is taking with regard to user's definitions in 
namespace std.
