in reply to Special cases make special community

The "split" special case I always think of is its behaviour with an empty regex, which is completely different to the regular behaviour of an empty regex, which is in turn a special case that does something I would never have guessed in a million years unless I'd read the documentation. :)

(I find it quite useful in split, but I don't think I've ever seen it used otherwise.)

    For the unaware, the general behavior of an empty regex is to function as the last successfully matched regex, if I am not misremembering.

    for(split(" ","tsuJ rehtonA lreP rekcaH")){print reverse . " "}print "\b.\n";
