Subject: calling a descendant's method

Hello,

is it possible in Ruby to make a method of a class calling another
method to always call the version of that method from the descendant?
I do not know how to put this more clear, so here is an example:

  class A
    def f
      g # what to put here?
    end

    def g
      "Haha"
    end
  end

  class B < A
    def g
      "Hoho"
    end
  end

  B.new.f  # i want this to return "Hoho", but it will return "Haha"

Thanks.

Alexey
