Thinking about what Zhang was saying about multiple-dispatch not being
inherently OO. I think he's sort of right. Multiple-dispatch need
not be confined to method lookups.
foo();
foo($bar);
foo($baz);
foo($bar, $baz);
sub foo () : multi {
...
}
sub foo (Bar $bar) : multi {
...
}
sub foo (Baz $baz) : multi {
...
}
...etc...
Obviously, there would be no inheritance. Otherwise, it's
just like multiple-dispatch where there's no superclass.
Handy, if it's not too hard to implement.

[Joseph] Schwern. "It's our duty."
