Out of curiousity, what do you do when the person hears your first question, and responds, I know you want me to talk about list context, but before we get to that, unless you really mean to have implicit argument passing, it is a good idea to avoid using the &func syntax. In fact even if you do, I prefer writing that as func(@_) for clarity...

Also what you should ask depends on context. Personally I avoid asking "Perl trivia". I would prefer to take a good programmer and teach them Perl than to try taking a Perl expert and teaching them good programming. (Getting someone who doesn't need teaching is, of course, preferable.) Given that I prefer to ask questions on strategies, algorithms, see them write some code I can go over for style, etc.
