If the cost of comparing $. to 10 is significant compared to the
rest of your loop, you're in the wrong programming language.
However, having said that:
my $meat;
$meat = sub {
$meat = sub { real body of loop here } if $. >= 9;
};
$meat->() while <>;
There. Happy? No more tests. And now you'll complain about the
subroutine call. :)
