... this seemingly useful idiom for casting array refs back to arrays.
... and for creating global symbols (with the creation points buried in functions) to lie in wait to ambush your sanity during your next 3 AM debug session.
If you're not dealing with module operations (e.g., export of package variables), what would be wrong (or less useful) with using the standard lexical @$array_ref $#$array_ref $array_ref->[$index] @{ $array_ref }[ $n .. $m ] etc. dereferencing operators/operations?

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).
