[boost] std::tuple vs boost::tuple clashes in C++0x

Just wanted to post a general comment, to boost library developers.

There are lots of names which in C++0x occur in both boost:: and std::. The big ones are tuple, make_tuple and array, but there are others (for example locking functions from thread).

I am fixing bugs which occur in the C++0x mode of clang/libc++, and the vast majority of these bugs are tests which write things like:

...
using namespace boost;
using namespace std;
....
tuple<int,int> t;

Even if you don't include <tuple>, a definition of tuple gets pulled in by <utility>, which almost everything includes.

Please don't write "using namespace std; using namespace boost;" in boost tests. You probably shouldn't write it at all :)
