Regarding \Z and \z. Now added. Thankyou for your suggestion.

I didn't think about pack/unpack but that's because it's something I so rarely use. It's also less likely to have appeal to the Java, Python and PHP members of the conference audience, whereas (so far as I know) Perl's regular expression syntax ought to be useful to all of those members.

A "No Java" message might get me into trouble, all things considered. ;)

Thanks again for your suggestion.

    That's exactly why I'd put it on a mug. Regular expressions is what people use all the time, and so they'll know most, if not all, of the syntax already. And since Perl regular expressions are firmly based on Henry Spencer's library, a lot of non-Perl users will not have problems with Perl regular expressions.

    OTOH, I don't use pack and unpack that often. That's why I need to look up its syntax when I do use it.

    In that same vein (or in the vein where I have my coffee injected)...

    The things for which I'm always going back to "perldoc perlre" are:

    (?=) positive look-ahead (?!) negative look-ahead (?<=) positive look-behind (?<!) negative look-behind
    In fact, I had to look them up again just now, to make sure I posted them right. (Having done this, maybe I'll be able to use them from memory next time.) These really are tremendously useful, and it would be swell to have them visible on my desk at all times (except when I'm drinking my coffee, of course).

    I'm reluctant to suggest removing anything you have already, and I suppose you'd need to shrink the font if possible (and abbreviate "positive" and "negative") to make more stuff fit. If that were doable, and you ended up with enough room for just a couple more things besides "[pn].* look-.*d", you could add:

    \p{...} unicode class ... [:...:] posix class ...
    (not much detail there, admittedly, but just getting the terms "unicode" and "posix" onto the mug seems worthwhile).
