You're right. Sorry, I was a little quick to correct the "," to "=>", but I think the comma works fine as you pointed out. I'm so used to using "=>" that at first glance I thought using the comma was illegal. The "as long as you know that the list has an even number of elements..." part is enough for me to use the 2nd version ("=>") since I know the 2nd one works all the time :-) In fact all the perl documentation on hashes shows the "=>" operator.
As I think you'll agree, in this code:
my %hash = ('a', 'b', 'c', 'd');
it is not clear that 'a' is the key referring to value 'b'.

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).
