I withdraw the seeming comparison to Common Lisp. I was trying to make a
more general point, but the implied comparison is not fair. Let's take Cecil
instead, since it was designed by people with extraordinarily good taste
(cc'ed), and since you recommended it as an example of multimethods done
right. On your recommendation, I read it. Because of its pedigree, I really
wanted to like it. In the end, I was reluctantly repelled by its complexity.
If it is representative of the complexity costs of multimethods done right,
I consider these costs to far outweight the benefits. Other things being
equal, I would chose not to program in Cecil.
