[Swig-user] Warning 503: Can't wrap 'operator <' unless renamed to a valid identifier

Warning message:

Warning 503: Can't wrap 'operator <' unless renamed to a valid identifier.

I have tried to wrap this function that is a part of the mycode namespace.

namespace mycode {
 class MYPROJECT_EXPORT Latitude
 {
 public:
  Latitude ( double value )
   : m_value ( value )
  {}
  double get_value () const
  {
   return m_value;
  }
 private:
  double m_value;
 };
 MYPROJECT_EXPORT bool operator< ( Latitude const& lhs, Latitude const& rhs );
} // namespace mycode

With the following line in the SWIG interface file:

%include "Latitude.hpp"
%rename(LatitudeLessThan) operator< ( Latitude const&, Latitude const& );

I tried it with the namespace 'mycode' and without it. Either way I
get the Warning. From the documentation it was unclear to me if I
should include the namespace
in the line.
