Lie,

I understand what you mean about metaclasses not being something that
everybody needs to master on an everyday basis. Unfortunately, I'm the
type of person that has to know how things work. I consider this an
unfortunate defect, due to the fact that I am unable to compromise and
let go even when practical considerations would dictate that is the
appropriate course of action.

I'm going to stick with this. I haven't even read the official
Reference manual, so maybe I'm getting ahead of myself though. My
plans are to read the reference manual, then selected parts of the
library manual, and take it from there.
