It doesn't work - I'm getting the same error as before (in the unpatched
ruby version):

bash-2.05a$ ruby mixin.rb 
mixin.rb:23:in `[]=': bind argument must be an instance of Array (TypeError)
        from mixin.rb:23

The problem is that the []= method remembers the class, that it was bound to
before, and a type error is raised.
