That's too bad.  Is it just the ones that are in block scope that
cause problems, or do the ones in namespace scope other than the
global namespace also get dumped into the global namespace instead?
Either way, probably having them in the wrong scope would probably be
better for users than not having them at all.  (Though I'm not an
experienced enough C++ programmer to know for sure how confusing that
would be.)  But it's definitely suboptimal.
