I've created an array of anonymous hashes
to act as structures to hold data from some files
I'm working on parsing.
For various reasons, I need to add an element
into the middle of the array that is the same
as the one before it except for some minor
modifications.
I'd been doing this with:
my $new_element = $hash_array[$index];
Of course, I've noticed that this just
makes $new_element a reference to the same
anonymous hash.
What is the best way to make $new_element
be a reference to an anonymous hash with
the same data as the anonymous hash in
$hash_array $index, so that I may
splice it in?
(Side question: When using splice and
replacing a run of 0 length, are new elements
put at the offset position, or after?)
Thanks in advance, wise Monks.

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).
