== What is a decorator ==

A decorator is a software design pattern.  Decorators dynamically alter the functionality of a function, method, or class without having to directly use subclasses or change the source code of the function being decorated.

For more information about the decorator pattern in general, see:

 * http://en.wikipedia.org/wiki/Decorator_pattern

== Debate about decorators in Python ==

The winning syntax as of now uses the '@' symbol.  There has been a long discussion about the syntax to use for decorators in Python.  See for example these threads:

 * http://www.livejournal.com/users/jcalderone/3913.html

== Examples ==

{{{
!#python

@classmethod
def foo (arg1, arg2):
    ....

}}}
