Subject: Re: More flexible inheritance

I tried to implement similar solution some time ago, in case with Foo - 
it may looks like that:

  class Foo
    instance_methods do
      def foo

      end
    end
  end

  Foo.instance_methods do
    def bar
    end
  end


For working code and specs please go to:
specs: 
http://github.com/alexeypetrushin/ruby-ext/blob/master/lib/ruby_ext/prototype_inheritance.rb
code: 
http://github.com/alexeypetrushin/ruby-ext/blob/master/spec/ruby_ext/_prototype_inheritance_spec.rb

It seems to works, but I prefer (and using actually) a little lighter 
solution, kind of mixins with sugar, you can find more details about it
