>From Python 2.0 Reference Manual, section 3.3.2:
"""
The following methods can be defined to customize the meaning of attribute
access (use of, assignment to, or deletion of x.name) for class instances.
For performance reasons, these methods are cached in the class object at
class definition time; therefore, they cannot be changed after the class
definition is executed.
