I do that without problems, I thought typedefs and using statements were
properly scoped. Using a whole namespace in similiar way with C++ standard
conformant compiler shouldn't bring out too much issues.. not that I would
recommend doing it, and naturally I would better avoid using same symbols
the std:: is using, ah, I see what this is about, sorry for wasting the
bandwidth. But atleast the GLOBAL namespace would be safe, until someone
decides to use namespace "bar" (the one inside which we would be using all
of the std..)
Just joking, I am not sorry, the point was that hand-picking some classes
like above can be handy now and then!
