I like using CGI::Carp even for non-CGI programs, because
you get the
timestamp and name of the script which can be awfully handy
if your program
has ended up being launched from cron and buried five levels
deep in a maze
of twisty shell scripts, all alike.

It doesn't half confuse the sysadmins when your Perl daemon
process logs to
syslog instead of STDERR. It's almost as if they've never
used any other
daemonised program in Unix before, or were expecting all
Perl to be
something along the level of Matt Wright's code.

I try not to give opinions on which exception handling
modules to use, but 
I do have a couple of talks on this:

http://axkit.org/docs/presentations/tpc2002/exceptions
.pdf
http://axkit.org/docs/presentations/tpc2001/exce
ptions.axp/a.pdf

(the first one is better than the second).

Matt.

I would be grateful for a copy of those slides if you still
have them (or
anyone else does).
