This is bad -- it's better than any workaround in clarity. In fact, I still 
don't understand why classes have so big overhead. Later, we'd have to 
revisit this topic, and try to optimize classes before abondoning them in 
performance critical part.

Well, comparing a list of targets, where target is a class instance, it still 
very hard.
