By my understanding (which is definitely not very thorough), the output would
be a run-time error. And I think that
$\ = "\n";
$i = 0;
for ( .. -1 ) {
next unless $_ > -10;
$i++;
last if $i > 2;
print
}
is supposed to print
-9
-8
How it would know to do that is beyond my ken, but I believe that is what it
is expected to do.

Leibniz never married; he had considered it at the age of fifty; but the
person he had in mind asked for time to reflect. This gave Leibniz time to
reflect, too, and so he never married.
