>Description:
if you want to inject an operator from a namespace into a file, you need to include the entire namespace.  I don't think this is correct.  See below for an example.  The line with is incorrectly handled is marked:


namespace foo{
  template<class X>
  int bar(X x);
  template<class X>
  int operator- (X x);
}

int main()
{
  using foo::bar;    // works correctly
  using foo::operator-;  // ** complains as syntax error
  using namespace foo;  // will inject operator-
}


>How-To-Repeat:

namespace foo{
 
  template<class X>
  int operator- (X x);
}

int main()
{
 
  using foo::operator-;  // ** complains as syntax error
 
}
