It always seems clearer to me when written as:

    str = "I am a string"
    def str.x
      puts "method illustrating singleton class"
    end

I understand that the method is really defined in the
anonymous singleton class associated with str but the
'def object.method' syntax is more self-explanatory
(to me) than the 'class <<obj' syntax.
