Thanks for the tip. That worked however, each class that has this mixed in,
must call super in its initialize function even though the class has no
"real" superclass. I don't suppose there is any way around that?

Just a tip: don't mess with "new" unless you really know what you're
doing.

$object_list = []
module ObjectDB
	# *args is for "accept anything"
	def initialize(*args)
		$object_list.push self
		super
	end
end
