For now, seems that you have to settle on Storable, as there are quite a few serious bugs in Clone.
However for long term, it seems Clone would replace Storable, so expect to migrate to Clone:
- Although Storable is also optmized, but its dclone is slower when compare to Clone's clone. This is easy to understand, as dclone is not the focus of Storable.
-
The dclone function in Storable is kind of quick-and-dirty solution, it simply serialize the data structure first, and then deserialize it to create the clone. Although it is optimized to share data between step one and two, it still does lots of things that are needed for serialization but not pure cloning.
The functionality of deep clone should stay in a seperate class.

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).
