Heres a couple of excerices you might try,
- Implement a binary tree using arrays as nodes , then reimplement using hashes. Operations defined should be depth first traversal (inorder, preorder and postorder) along with breadth first traversal, insertion, deletion, and merge operations.
- Convert the previous implementation into a fully object oriented one.
- Change the binary tree to a 2-3 tree.
- Implement a version of Data::Dumper. Try to add a feature that Data::Dumper doesnt have, but dont try to replicate all of the functions it does.
- Implement a huffman encoder. Try not to use any of the methods used on site. :-) Then check against the site.
- Write a game, pick any simple game like hangman or the like
- Take any program you have written in another language, and rewrite it so it runs under perl.
- Take an existing program and try to rewrite it without using block style loops. map{} grep{} and modifiers are ok.
Some or all of these are what I found particularly instructive as i learned 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).

are good places to start.
