If you develop a Perl program in a CGI

use CGI::Carp 'fatalsToBrowser';

It will make the browser display more meaningful error messages.

That may not always be a good habit, since the error messages are
meaningful only to the programmer:

http://schwern.org/~schwern/cgi-bin/unix2vms/

One can look for the messages produced by "die" in the error log too,
and if the code is in use by people other than the CGI programmers
(which it probably will be) it's probably a better bet to not use the
above outside of testing, since it will produce something meaningless
and confusing.

I wouldn't find it meaningless and confusing. It is quite clear that an
error has occurred, that is neither meaningless nor confusing. It gives
extra information, but I think I (being hypothetically not a CGI
programmer) would know enough to expect that this is meaningful to someone
else, if not to me, and that if I wish to discuss the error with that
someone else, it might be helpful to quote parts of it to them, so in that
way it is meaningful as well as not confusing.


But, YOU won't be there. The whole idea is programmed error recovery.
To just die, unless you can't recover is not an option in the corporate world.
Built in recovery algo's are manditory in the money world.
