Just now I needed a +=3 list loop, and I made a hash of anonymous arrays:
my %hash = (
'one' => [ '1', 'first' ],
'beta' => [ '2', 'second' ],
'zeta' => [ '-1', 'last' ],
);
while ((my ($key, $value)) = each %hash) {
a_func_w_3_args($key, $value->[0], $value->[1]);
}
The big plus for me in this format was that it makes the step 3 iteration of the data painfully obvious. Hopefully, the code isn't too painful, tho.

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).
