The implements clause isn't needed. Just put the methods in. Ruby does 
not bother with this kind of compile time checking. At runtime when you 
call a method on an object, the method may or may not even exist. If it 
doesn't Ruby raises a NameError exception.

For something maybe a little better than the Java implements clause, 
look in the pickaxe book to learn about mixin.
