Sorry, but you'll have to change again ;-)

Ruby doesn't really differentiate this way. The body of the class
definition is also executable code:

     puts "Before"
     class Dave
       puts "In Dave"
     end
     puts "End"

  => Before
     In Dave
     End

The thing that might be confusing is remembering that Ruby finds its
methods dynamically. It doesn't matter when a method is added to a
class or one of of its ancestors, it's simply a question of what's
present in the ancestor chain at the time the method is called.
