<p>[GrandFather] and [davorg] have your answer above. I just wanted to add that it often reads better to label your loops with what they're iterating over, rather than their structure.</p>
<p>For example, say you're processing files and records line-by-line. You could do this:
<code>OUTER:
while ( $more )
{
INNER:
while ( $still_more )
{
# ...
last OUTER if $done_with_files;
last INNER if $done_with_lines;
}
}
</code>But it reads better with a change in labels:
<code>FILE:
while ( $more )
{
LINE:
while ( $still_more )
{
# ...
last FILE if $done_with_files;
last LINE if $done_with_lines;
}
}
</code></p>
