Several of the differences between Perl5 and Perl6 are
intended to reduce the amount of dereferencing you have
to do. So I like thinking of this syntax change as just
being Yet Another way of indicating to people that you
are supposed to be thinking in terms of more immediate
data structures and less about having a reference that
you dereference.
YMMV, but that is true to the usage of both . and ->
in C.

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).
