From a evil-software design overlord perspective, I don't believe in wantarray being a good idea at all -- but you are probably glad that I'm not in charge. Technically, a function could do something entirely different based on context, not just in return type, and should it really be able to do that...

Perl says do whatever you want, but in the general case, that's asking for trouble. Feel free to disagree, that's fine, but there are many aspects about Perl that make it sloppy. Sometimes these are the same reasons that make it flexible and cool, but sometimes not.

So if people can argue Perl OO is ugly (most would agree), I can argue that wantarray is ugly... Never mind that wantarray seems to imply a true/false value from a design standpoint but actually returns undef, true, or false -- it's a three way statement.

    [erix]: (eh, I meant the single-slit experiment)
    [james28909]: what if our whole universe is the result of someoneviewing the big bang before it happened? and BANG, wave function collapses and all that matter comes out and creates the universe
    [james28909]: who knows though
    [holli]: There is a book called "Cosm" in which something like that happens. A particle accelerator accident creates a new universe in which time goes superfast
    [erix]: tall story, jim
    [james28909]: " I'd even let him grab my mums pussy if that helps :-D" im dead xD
    [holli]: clicky
    [shmem]: "universe in which time goes superfast" - hmm, light behaves like syrup there, I guess
    erix chuckles at the existence of a nebula award
    [holli]: relative to ours.
