here's the whole new chunk of code:

=head1 Testing intentional exits

For developers of Raku packages, it is sometimes useful to provide an intentional
exit of the code path for a specific condition which can be indicated by a
unique, numerical exit code in the POSIX range of 1-127. Such is provided by 
test L<C<exits-ok>|/type/Test#sub_exits-ok>. Its use is demonstrated in the following
subroutine:

    sub apply-factor-to(Numeric $num --> Numeric) {
        unless $num > 1 {
            say "FATAL: sub 'apply-factor-to' input is $num, it must be > 1";
            exit(3);
        }
        $num * 2.0;
    }

That can be tested like this:
    
    use Test;

    exits-ok {
        my $x = apply-factor-to -2;
    }, 3, "got the expected signal 3 for invalid input";
