This is one of those things on which it is quite hard to find any good docs.

How does this formatting / style look? Is it readable enough?

Also, is it a bad thing to throw an exception in a ternary like that?

I'm trying to incorporate advice from Damian Conway's PBP, but did I succeed?

sub xyz {
    my ($ttt, $xxx, $yyy)
        = @_ == 2 ? (undef, @_)
        : @_ == 3 ? @_
        : croak('Not good.')
    ;

Thanks, much.
