all cases are handled by single dispatch; 0.9% are handled by double
dispatch; 0.09% are handled by triple dispatch; ...
I'd tell any language designer - don't worry about multiple dispatch.
Spend that time on anything else, it'll be better invested.

I agree with you, I doubt there are that much cases where more than
double dispatch is required.
But they make nice language puzzles. :)
