With particular reference to Re^3: How would you do it? Re ARGV, fundamentally!, which is your favourite perfectly legal and well documented (but possibly not terribly known) Perl feature that in your opinion would deserve a comment in "production" code, whatever that is for you?

I'm not fully convinced about the one pointed out by merlyn himself in the above mentioned node, but one possibility I was thinking aobut is the .. in scalar context (see perlop).

Update: s/cmt/comment/ in the text of the node. (Guess it's far too late for the title.)
