From a posting of mine I made in 1998 in one of the Perl groups:
And you can do that in Perl as well:
my $n = int (($count + 7) / 8);
goto (qw !LABEL0 LABEL1 LABEL2 LABEL3
LABEL4 LABEL5 LABEL6 LABEL7!) [$count % 8];
{
LABEL0: print "0\n";
LABEL7: print "7\n";
LABEL6: print "6\n";
LABEL5: print "5\n";
LABEL4: print "4\n";
LABEL3: print "3\n";
LABEL2: print "2\n";
LABEL1: print "1\n";
redo if -- $n > 0;
}
It's certainly legal to jump into a bare block, and bare
blocks are looping constructs as well.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
