The issue seems to be to justify practical use of multi-methods over
traditional OO programming with virtual functions. Remember that the
latter has been the core of OO programming for decades. I do not know
even how to think about designing software using multi-methods as
opposed to virtual functions. Without some serious practical benefits
about the 'when' and 'why' multi-methods would ever be used in
programming design it is hard to justify the idea, as clever as it seems
to be. Perhaps it is an idea that has appeared before its time and it
just needs some actual programming demonstrations which show its
advantage before programmers become interested in it. Nonetheless I
would like to thank you for bringing an implementation forth, even if
its practicality eludes me.
