No Ralph, i unspecifically meant multiple nested loops where some
inner has to restart/continue the outer (at some point).
So a bit like that of "man perlsyn", but with deeper nesting

       If you need both "next" and "last", you have to do both and also use a
       loop label:

           LOOP: {
               do {{
                   next if $x == $y;
                   last LOOP if $x == $y**2;
                   # do something here
               }} until $x++ > $z;
