Ouch! Precisely what I wanted to avoid: a modification in the number of items. Well, you could export a constant for this number, whether it be 2 or 5.
BTW if memory efficiency is what you're worried about, why don't you just use 1 scalar for each item? After all, these are all just integers, so messing with pack()/unpack() or vec() would allow you to combine them, in one scalar. Only an 8 (or 20) byte
string per item! The joy! The savings! (The pain!)

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).
