NAME
Fatal - replace functions with equivalents which succeed or die
SYNOPSIS
use Fatal qw(open close);
sub juggle { . . . }
import Fatal 'juggle';
DESCRIPTION
Fatal provides a way to conveniently replace functions which normally
return a false value when they fail with equivalents which halt execution
if they are not successful. This lets you use these functions without
having to test their return values explicitly on each call. Errors are
reported via die, so you can trap them using $SIG{__DIE__} if you
wish to take some action before the program exits.
The do-or-die equivalents are set up simply by calling Fatal's
import routine, passing it the names of the functions to be
replaced. You may wrap both user-defined functions and overridable
CORE operators (except exec, system which cannot be expressed
via prototypes) in this way.
