Hmm :) What I'm trying to do is ensure that only the object which
created another object can call it's methods. For example, object A
instantiates object B. In object B's initialize method, I would set an
object variable (@creator), referencing the object that called .new. On
method calls, I would "raise 'Method called by non-creator' if [insert
method to get ref to caller object].id == @creator.id"

Is there another way to do this?
