Is over-writing $! a good idea?

The errno values that pfaut(++) mentions are there for a reason.

What is wrong with supplying your error message to die (or warn, or any of the Carp methods) in the normal way:

die "Custom error messages are good!" if $condition;

You don't have to include $! in your die statements, if you don't want to.

Alternatively, you can install a __DIE__ handler to override the default behaviour of die: 

#!/usr/bin/perl

use strict;
use warnings;

local $SIG{__DIE__} = sub { die scalar localtime(), " " , $_[0] };

die "Argh!";

produces: 
Sat Jan 25 00:40:36 2003 Argh! at ./custom_die.pl line 8.

That way everyone learns.
