I call this the "Use what you already know" concept. I once saw in a code review a bit of code from someone you didn't trust arrays to know how many elements were in them. It looked a lot like:
my @array = ();
for( my $i = 0; $i < 10; $i++)
{
$count++;
push @array, $i;
}
print "There are $count elements\n";
I've seen the same thing for hashes too, since some people don't read the perlfunc entry for keys().
I'm still waiting to see some Perl code on The Daily WTF?

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.
