This is fixed in top-of-tree Clang:


t.cpp:10:15: error: call to function 'operator<<' that is neither visible in
the
      template definition nor found by argument-dependent lookup
    std::clog << t;
              ^
t.cpp:15:17: note: in instantiation of function template specialization
      'log<N::X>' requested here
  template void log(const X&);
                ^
t.cpp:13:17: note: 'operator<<' should be declared prior to the call site or in
      namespace 'N'
  std::ostream &operator<<(std::ostream&, const X& x);
