In C++, which must be resolved at compile time, the overloading resolution

However, you are assured that everything is brought to your attention at
program build time, before run time, so complaining is not as serious as a
run-time error where you might prefer DWIM.
Perl 6 is the same, just at runtime with actual types of actual objects.
That's it.
Indeed, Perl 6 threw out Manhattan distance a couple years ago. Do we
have to spec everything that Perl 6 ever was but isn't now? :)

No, just point me to what it says now. Or the scraps so I can collect
them together and "say" it during my productive period.
When I mentioned this before, there was big flack over mentioning the
way C++ did it. I think that must have been miscommunicated, since I
wasn't even talking about summing all the arguments when he brought up
"Manhattan dispatch".
