Can you be more specific? Not trying to be difficult, just truly
confused. The lists and sets and stuff seem quite simple to me.

Ah, now this is interesting. Lots of people have complained that the
swap operations, etc are not the way they'd have written the interface.
However, the more common way to write it creates a lot more garbage and
runs slower--I received a paper a while back from a person on the net
who advocates structural swapping as the basis of almost all data
structure design because it is so much faster; the Booch components use
this same approach. You can build a more abstracted interface on top
if you are willing to sacrifice space/speed.
