Stages of error handling:

1. Hey, this is easy - just grab the return code, and use it...

   $rc = func();
   if ($rc != 0) {
     die "Failed to func!";
   }

2. Oh, neat! Exceptions!

   eval {
     func();
   }
   if ($@) {
     die "Failed to func: $@";
   }

3. Exceptions/OO are da bomb! Look at this!

   use Error::Handler;
   $rc = func();
   if (not $rc->ok()) {
     die $rc->error_msg();
   }

4. Damn, that's way too much work...

   $rc = func();
   if ($rc != 0) {
     die "Failed to func!";
   }
   [download]

At least, that's my experience...
