    Hmm... goto &func is really, really useful in an AUTOLOAD. I agree that goto LABEL is really bad. And its lots faster and slightly better structured to do redo LABEL instead.

    The redo LABEL trick is something I'm using in a Scheme implementation I'm working on. It's sort of horrible, but it buys me tail call optimization and (coming soon) 'real' continuations, so I'll make the trade.

        Oh, don't worry about that Piers. We knew it was you. Who else is implementing Scheme in a version of Perl not yet released?

        Cheers,
