You say that for my $x (0 .. $#arr) is "better" than for (my $x = 0; $x < @arr; $x ++). Now, I don't care much what you find better, but since you have a preference that you find important enough to advocate, I'm interested in why you find your preference "better".
It's even optimized to not create the list.
Yeah, because it's special cased. The C-style loop doesn't create a list at all, and is even "optimized" in older versions of Perl.

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).

or How to display code and escape characters
are good places to start.
