Quesion about the proper use of __slots__

[Zefria]

Well, my computer tends to run at about 497 to 501 out of 504 MB of RAM
used once I start up Gnome, XMMS, and a few Firefox tabs, and I'd
prefer not to see things slipping into Swap space if I can avoid it,
and the fighter data would be only part of a larger program.

And as I said, learning how to use __slots__ is important enough to
hazard a premature guess this time around. If I mess up, the worst that
happens is that I have to write down a new variable name in two places
instead of one now.
