Decorators are very wonderful things, but if used as this article shows, they destroy the method signature of the function; fibonacci() goes from being a function that takes one argument to a function that appears as if it will take as many arguments as you give it. (That's the *args syntax; it collects all the arguments into a list.) Usually this is not a problem, but some people want to see the correct method signature when they look up the documentation (often auto-generated) for a function. And there are some programs that inspect the method signature and expect it to be correct. http://www.phyast.pitt.edu/~micheles/python/documentation.html http://www.phyast.pitt.edu/~micheles/python/documentation.ht... provides more details on this subject, as well as a library to mitigate this problem. I believe functools.wraps in python2.5 also solves this problem: http://docs.python.org/lib/module-functools.html http://docs.python.org/lib/module-functools.html
