I think you're assuming everyone will code the way you want. If you're
going to force everyone to code this way, why not just have them code

  void add_char( std::string& str_, char ch_ )
    str += ch;

  int len( std::string const& str )
    return str.length();

What is the added value of the proposed class? It's not that it forces
people to change the value if it's used:

  int len( in_out< std::string > str )
    return static_cast< std::string& >( str ).length();
