Metaclasses seem more and more like a good way to go.  As Python
progresses, metaclasses will be more and more possible, because of the
unifying of types and classes (I'm not *exactly* sure how it helps, but I
did read it someplace, and it vaguely make sense; but enough talking about
things I'm not sure of).  However, TransWrap implements an 'old-style'
type of Metaclass that relies on C extensions.  I'm not too keen on
writing C extensions for Python (or Perl or anything, for that matter,
unless it is for algorithmic efficiency).  But there are means to
implement Aspects in pure python (as described in the paper I mentioned),
so I'm going to investigate those.
