Test::More is typically used to compare two thingies, and report whether they are equal or not. And that's what you seem to be doing in your post.
IMO, that's a hard way of learning things. I rather want to see what is calculated, not just whether what was calculated actually matches what I think it might calculate (specially when you are learning-by-trying, by the time you can a reasonable prediction of what the output will be, you're almost done learning).
For regexes for instance, inspecting $& is far more informative than guessing what $1 will be. And, for failures, I can learn far more from the output of use re "debug"; that I can from Test::More saying not ok.

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).
