Cute 'findBest' with iter and fold and without evil copies.
use std::num::*;
// Given a collection and a score function, find the item with highest score.
fn findBest<'t,T,C:Ord>(src:&'t [T], scoreFunc:&fn(x:&'t T)->C)->Option<(&'t T,uint,C)> {
let mut it = src.iter();
let mut i = 0;
match it.next() {
None => None,
Some(first) => {
let firstScore = scoreFunc(first);
