Just for fun, I decided to map out a bit of the region beyond pack's normal range. The results were... interesting.

Besides the panic: memory wrap and Can't localize through a reference, one other thing stands out: pack u78 uses a space as the delimeter. In cases where you can't quite get your code to fit into a u45 format (starting with an m), it's a viable alternative, and has actually been the shortest construction I've been able to find for more than one challenge.
The run of chr(0) from u83 - u95 is unfortunate, though. An eval'd string beginning with the null character seems to terminate immediately, without error, for whatever reason.

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).
