Yes, that was the point.  Of course that assumes you're satisfied
with hand-waving.  But I want an engineering design (pattern?)
for a maintainable, extensible, robust understandable package.
I want someone to show me how multi-methods makes that easier.

If you suggest using the MOP then you're basically agreeing that
multi-methods are not useful for real systems.
