And so you can see it in action, here's a test/demonstration script for this module. 

#!/usr/bin/perl -w

#
# Test of Alarm::Concurrent - Written by Cory Johns (c) 2001

++$|;

BEGIN {
  # This will be saved and activated when
  # Alarm::Concurrent is imported.
  alarm(1);
  $SIG{ALRM} = sub { print "Legacy alarm." };
}

use Alarm::Concurrent qw( :OVERLOAD :ALL );

setalarm(6, sub { print "BONG!!!" });

alarm(2);
sethandler(sub { print "bing" });

MyPack::doalarm();

# Alarms set for the same time go
# off in the order you set them.
setalarm(4, sub { print "!" });

package MyPack;

sub doalarm {
  # Alarm is overridden in _all_ namespaces.
  alarm(4);
  # $SIG{ALRM} has been taken over.
  # It now calls sethandler().
  $SIG{ALRM} = sub { print "bong" };
}

package main;

for(1..6) {
  print "Second $_... ";
  sleep 1;
  print "\n";

Seasons don't fear The Reaper.
Nor do the wind, the sun, and the rain.
We can be like they are.
