Comment(by watson1978@…):

 I had improved this issue in
 https://github.com/MacRuby/MacRuby/commit/677f704206497cbe9d65d7ba088a8d283d283c7f
 [[BR]]

 {{{
 module Dog; end

 module Core
   #include Dog
 end

 module Factory
   include Core
 end

 class Cat
   include Factory
 end

 p Cat.ancestors
 }}}

 {{{
 $ ruby19 t.rb
 [Cat, Factory, Core, Object, Kernel, BasicObject]

 $ macruby t.rb
 [Cat, Factory, Core, NSObject, Kernel]
 }}}

 but, still strange ancestors are display if there is more complex
 including.

 {{{
 module Dog; end

 module Core
   include Dog
 end

 module Factory
   include Core
 end

 class Cat
   include Factory
 end

 p Cat.ancestors
 }}}

 {{{
 $ ruby19 t.rb
 [Cat, Factory, Core, Dog, Object, Kernel, BasicObject]

 $ macruby t.rb
 [Cat, Factory, Dog, Core, Dog, NSObject, Kernel]
 }}}
