I don't know whether you can use multimethods to do it, but if you
can, it would probably go something like this:
sub wonk (@list: &code) is multi {
grep {!code()} <~ @list
}
So C<wonk> would be called like a method, but still not have access to
C<Array>'s private attributes as it's not a part of the class.
I don't know whether I like this or not.
