|Do you mean ‘continue’ which re-tests the condition or more like Perl's

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;
}
