I no longer fear the ternary operator, so this is readable enough. There must be a clearer way to express the logic, though. Having the first parameter be undefined when @_ isn't quite long enough, and croaking if @_ isn't exactly the right length ... it makes my brain hurt a little.

What about switching around the order of the parameters?

sub xyz {
    my ($xxx, $yyy, $ttt) = @_;

    # You could also say -> if( !$xxx || !$yyy )
    # if you wanted to avoid 'unless' like the PBB says
    unless ($xxx && $yyy) {
        croak('Not good.');
    }

    # ...
}

This way we don't have to enforce a specific size for @_, too. Double bonus.
