I guess Dave answered excellently in [ruby-talk:26803], so that you
need no more explanation from me.

There's one more thing I can tell you.  "type" in Ruby is just an
illusion.  It doesn't really exist, but in our mind.  We emulate it
sometimes using a class of an instance, sometimes using set of methods
that an instance can respond.

If it is merely an illusion, why should we care that much?
