Sure, I hope it was clear that I "kind of" agree, since I included a
smiley and mentioned that I'm aware of the idioms. Clearly, MD is
"cleaner" at some level but that argument could be used for including
every feature in a language.
I'm still wondering if anyone (Dmitry?) can come up with some good
(natural, commonly occurring, etc.) examples which use triple or
n-tuple dispatch where n > 2. All of the examples I've run into so
far are double-dispatch.

Well, surely you read the note about the ESA project which eschewed
Ada in favor of C++ on account of the inability to do Java style
MI of interface in Ada? That may not count as customer demand, but
it is an interesting data point nonetheless.
