It is contrary to what the documentation says. I think it also doesn't
make much sense in C++ if the return type results from a template
substitution. For example, the following case is rather common:

  template <typename T> class Array {
    T& operator();
    T operator() const;
  };

This class will trigger a warning if instantiated as Array<const double>
because the return type of the second operator() is now 'const double'.
