# A SimpleDelegator instance can take advantage of the fact that SimpleDelegator
|

|
# is a subclass of +Delegator+ to call <tt>super</tt> to have methods called on

|
# the object being delegated to.

# class SuperArray < SimpleDelegator

# Here's a simple example that takes advantage of the fact that

|
# SimpleDelegator's delegation object can be changed at any time.
