- The inherited instance variables preserve their offsets.
- The new instance variables are placed at the end of the inherited
variables.
- The inherited methods preserve their offset, even when they are
redefined.
- The new methods are placed at the end of the method table.
- Even though the compiler does not know the exact type of a referenced
object, it will look for an instance variable or a method at
a fixed offset.
