Another possible style, which I prefer, consists in writing the comma at the beginning of the next line, not the end of the
previous one.
That reminds me of the professor who gave us our first programming
classes back in university. He would write the semi-colons
before the statements, not after them. (This was in Pascal,
where semi-colons are statement separators, just like in Perl).
This style also allows easier editing of the hash.
Really? How? I see as disadvantage that if you remove the
first item you need to modify the next line. Or if you insert
an item at the beginning, you need to modify the next line too.
The big advantage of putting a comma after the items is that
you can always put a comma there, and don't have to do special
things when adding or removing elements - not even at the beginning
or end.

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).
