Yep, this was about the conclusion I came during the night.

Well, me neither :). But if I reflect OO-things from C++ or Java I think
they don't allow parent class to know the real class is actually a child
when calling.

class Foo
  def foo
	p self.type
  end
end

class Bar < Foo
end

Bar.new.foo

In those languages call to Bar.new.foo forces Foo#foo to think self is
actually an object of type Foo, not kind_of? Foo. This was the surprise.
