If you want to read about OO design patterns in Ruby take a look at
"Design Patterns in Ruby" by Russ Olsen
(http://safari.oreilly.com/9780321490452).

Ruby is an interpreted language. There is no compile time check. AFAIK
if you want to implement something like abstract classes, you can use
the NotImplementedError exception:

class Foo
    def bar
        throw NotImplementedError.new("Implement me!")
    end
end
