  • 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 t

    • 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!
