Ok...
1. Method objects are referenced from method slots like any other object
from an data slot.
2. After cloning an object with a method slot, the original and the
clone share the method object.
3. Changing the method via the editor of one of the objects will create
a /new/ method object for this object.
Makes sense. :-)
