Something similar I often do in CGI programs and other utilities that are not attached to the terminal:
BEGIN {
open STDERR, ">", "/tmp/$0-$$.log";
}
and then all die and warn messages go to the log file in /tmp.
To get this to work with Sys::Syslog you would need a little more machinery:
BEGIN {
sub SLH::PRINT { syslog("err", $_[1]) }
sub SLH::TIEHANDLE { return bless ["dummy object"] => "SLH" }
tie *STDERR => "SLH";
}
And then everything written to STDERR gets passed along to syslog.
Disclaimer 1: I didn't actually try this.
Disclaimer 2: I never, ever use software written by Eric Allman.

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).
