If I have an object which I know to be a subclass of a subclass (at lease)
and I want to override a method, I can do it in that object's class and
all is well.  But if I can override the method higher up I get more power
from my change.  My change may not just affect Fixnums, but it might be
able to work on all numbers, for example.  Given the reflection abilities
of Ruby, can I ask an object which class really handles a given method?
Then I know where to make the change.
