I was assuming that Method#origin and Kernel#origin would both
return a reference to the class/module.  In fact, Kernel#origin
is really just  short for method(name).origin and of course
you can just call object_id on the module/class reference as needed.

It appears that you are viewing the (proposed) return value of
Method#origin and Kernel#origin as a string and not as a reference
to the module/class itself as intended by myself and the other
posters.
