That isn't really solvable, as function names can be
generate during run-time, using "eval" for instance,
but also with: $obj -> $method, or because
they are exported to another package (which happens after
such a package was compiled).
Also, functions can be called from other packages.
Not to mention that there are lots of functions that
are never explicitly called, like BEGIN,
AUTOLOAD, DESTROY, FETCH
and import.

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
