Subject: Returning an instance from a different class from new

[For some reason I am no longer subscribed to ruby-talk and I don't get any
mail back from the ctl address, which is why I have to use my provider's
crappy newsserver :-(]

How do I make the following return Bar instead of Foo?

class Foo
  def initialize(sel)
    case sel
      when "1"
        return Bar.new
      when "2"
        return Baz.new
    end
  end
end

class Bar < Foo
  def initialize
    self
  end
end

class Baz < Foo
  def initialize
    self
  end
end

o = Foo.new("1")
p o.type

Thanks,
Jos
