Oh, and just looking at this again after your reply, I noticed the the
instance_eval isn't even necessary since we're inside the instance in
the body of instance_send anyways:

  class Object
    def instance_send( ... )
      send( ... )
    end
  end

That removes one level off the call stack. The stack in this
circumstance would be one deeper than send with an explicit receiver,
but not as deep as with an exterior instance_eval (since you have to
enter instance_eval and then enter the provided block from there). I
don't think the slight inefficiency compared to send with an explicit
receiver is a problem. If it does turn into a problem, one can use
#method and Method#call instead, right?
