in reply to Benchmarking "Are all these characters in this sentence?"

Here are the results using perl, v5.10.0 built for x86_64-linux. Interesting changes in ranking.

I'm surprised tye's /./gs solution took such a hit. The unpack and index solutions did get a bit faster, but not much. Weren't regexes supposed to have gotten a bit faster in 5.10?

    I'm having a lot of fun with this... I was so sure slicing was going to beat everything else, how wrong!

    I expected 5.10.0 to shuffle things, but not this way, thanks!
