This looks like a really useful feature. More ways to do a thing helps you understand the thing you do. One look at the Documentation and (de-)referencing seemed more like it's own operation, rather than something that needs to be done differently for each data structure or variable type or scoping function or Thing.
Perl 6 is object orientated, and this feature appears to be aligning Perl 5 with some of that kind of thinking. But objects in Perl 5 are not the same as objects in a fully qualified objective language. Though tends to be preferred for reasons of mnemonicisity and security and so on.
The perliness of this is that it is using method invocation to implement a (de-)referencing operation in a somewhat recursive manner. As to invoke a method on something, that thing needs to be a reference. So there's potentially also some auto-vivication at play here with the assignment capabilities.

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).
