It appears that every object has its own copy
What this means is:
- An instance function cannot be invoked in the
absence of an object instantiated from the class.
- An instance function can only be invoked by way of
the specific object to which it belongs.
- When the code in an instance function references an
instance variable of the class, it actually references the specific copy
of the instance variable belonging to the specific object on which the
function was invoked.
