--- Comment #6 from Ilya Konstantinov <ilya.konstantinov at gmail dot com> ---
This bug causes an error using llvm's libc++, e.g.:

#include <string>
void foo() {
  string::iterator it; // friend-declares vector<_Tp,_Alloc>
}

#include <vector>
using std::vector; // <-- error: 'vector' is already declared in this scope
