Subject: Delegate to allow subclassing Integer, Float

I have the following code using facets/basicobject with 1.8,
and want to know what the equivalent would be for 1.9:

class Real < BasicObject
  def initialize(r)
    @__value = r.to_f
  end

  define_method(:class) { __self__.class }      

  def send(meth, *a, &b)
    # Ensure that normal sends go to __self__, not @__value
    __self__.send(meth, *a, &b)                 
  end

  private
  def method_missing(meth, *args, &block)
    @__value.send meth, *args, &block
  end
end

(and similar, defining Int for integers).

This seems to be ok with 1.8, but 1.9 doesn't have __self__.

Any thoughts?
