I know what you mean, but given (sigh) how often this'll be used, I think it's better to Huffman it. If anyone has a brilliant idea for a shorter keyword than default, I hope they'll send it in.

    I pondered that for a bit but the best I could to was orelse. But that's even worse. :(.

    Not shorter, but I think it's easier to read and a lot better:
    given $foo { when 1 { ... } when 2 { ... } when we have tried all other options and really have nothing left but this last resort { ... } }


    :)

    How about nothing?
    given ($foo) { when (1) {print "One";}; when (2) {print "Two";}; print "Didn't fit any case we know about"; }
    Indent to taste.

    UPDATE
    I don't think that "normal code" will often see a difference. While I can dream up situations where I think it matters, in all of them you are doing evil, awful things that you probably shouldn't. (Like using a default to shortcircuit out of a function.)

      That is already defined to work but doesn't solve the problem of the presense of a real "default" block changing the handling of exceptions.
