  • Your reasoning is flawed. You are assuming that there is one positive match in the set, and that the set is small. On such a small set you're right any isn't any faster, but superior algorithms rarely show up on small datasets.

    If you would test this with a larger dataset, any would come out much better. On my computer, using the list 1..1000 and a needle of 500, it is in fact faster. The advantage only gets bigger when the haystack gets bigger.

    You're right it's not always better, but it is when it matters the most.

    • I agree. With such a small set no method is going to take an irritatingly long time. Since you have the program handy could you give it a quick tweak to use a bigger array and re-post the results?

      I also agree with autarch that any reads better, as a way of signalling programmer intent. I'd probably use the any from Perl6::Junction rather than List::MoreUtils; any chance you could add that to your testing as well? Thanks!
