	My turn, hmmm.

	The problem is that I cannot give where is "class_added" example
	used, because it's brand new... :-)

	But I can imagine that it can be handy for:
		- introspection
		- logger (to monitor what it happening)
		- the situation when the "inherited" callback cannot be
		  used - when people need to inform other
		  classes/modules (benefit of different "receiver" than
		  "inherited" has)

	Uff - this all is a little dumb examples, but hopefully somebody
	can think of a better example.

		Michal


PS: to all: HELP FOLKS! :-)
