Let's re-phrase the question to: Is there a way that I can test prior to running a progrgam whether or not a regular expression will compile.
The answer is Yes, use the -c flag when invoking perl. You can use: Perl -c myprogram, or you might make the program read in the regex from an external file ... possibly specifying which file on the command line. Then you only have to test the regex file: Perl -c regexfile.

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).
