The infuriating thing was that it actually seems to work
Sure, it "works", but it's certainly not right:
$ perl -MData::Dumper -we 'my %hash = {}; print Dumper \%hash'
Reference found where even-sized list expected at -e line 1.
$VAR1 = {
'HASH(0x814cc20)' => undef
};
It generates a warning and adds a useless entry to the hash. I can't imagine that's what the contractors wanted to do. :-)

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.
