This is probably just a minor nit, but thought I might learn something. My understanding is that there is very little difference (from the perl interpreter standpoint) between:
my %hash = ('a', 'b', 'c', 'd');
and
my %hash = ('a' => 'b', 'c'=> 'd');
Advantages I can think of for the first representation are:
- As long as you know that a list has an even number of elements, you can use it as a hash.
The advantages I can think of for the second representation are:
- The => reads better from a maintainability standpoint
- you don't have to quote the key. For example:
my %hash = (a=>'b', c=>'d');
Essentially => is syntactic sugar for ,.
Update. Missed a tic.
"Look, Shiny Things!" is not a better business strategy than compatibility and reuse.

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).
