    I love it!

    Could you please change the <code> to a <pre>, though? This wraps around, which is ugly. I think a tag change may fix it. screenshot.

    Juerd # { site => '', do_not_use => 'spamtrap', perl6_server => 'feather' }

      Unfortunately, <pre> breaks all the square brackets. It's probably sufficient to point out that hitting the download button gives you a clean copy.
        Ah, but the simple fix for that is to s/\[/&#91;/g. But yes, downloading does work too.
