I don't know about the "not much effort" part, but in theory, this is
something I'd support.  We talked about doing this for the Zope3 i18n
effort, but the primary reason we didn't was due to performance
concerns.  After talking with Fred, I came to understand that much of
the code's current obscurity is due to optimizations to make TAL
perform at least as fast as DTML.

So while I'd love to have the code be cleaner and more pluggable, we
have to decide 1) if we're willing to give up some performance to
acheive this, and 2) if not, can you provide a design and
implementation that will "perform adequately"?
