It makes some sense to me. My preference has been for the @{ ... } style of dereferencing. That style becomes cumbersome when ... is a large expression. I would hit the end of the expression and bounce back to the start of the block to remind myself what was needed. My workaround for that was to add temporary variables whose only purpose was to make @{ ... } easier to read.
...->@* reduces the need for those temporary variables because it allows a clear "treat this thing right here like an array." I don't know if this is better or worse, considering that we've been doing it the other way for years. It's just different. I'll try it, because I am a sucker for syntax.

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).
