I've been reading up on aspect-oriented programming (quickstart link
would be www.aspectj.org, although that's a bit Java specific). It makes
a lot of sense to fiddle around with someone else's class code at
run-time. 

Also, don't forget that with dynamically typed languages like Python,
you often aren't interested in types at all, just in the kind of methods
an object offers you. So mixing in methods, even at run-time, can be
a very useful operation in order to make the object accessible to
more other objects (who expect these methods to be present). 

Besides, it's fun.
