Lists are surrounded by brackets....
Not rvalue lists! Commas, not parentheses, produce literal rvalue lists. The three array references in this variant of that code are a list just as much as in the original version:
my @compass =
["NW", "N", "NE"],
["W", "center", "E"],
["SW", "S", "SE"],
;
The difference between the two examples is the precedence of the assignment operator compared to the precedence of the comma operators.

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).
