Touchable.pm is not yet published, but perlmonks deserves a preview
Just by including this incredibly simple module
you can prevent unwanted access to
your perl programs and
protect your compiled application from
unintended double clicks. Here the code and example usage
#!/usr/bin/perl
use strict;
use warnings;
package Touchable;
exit 0 unless (stat ($0))[9] && (($^T - (stat ($0))[9] ) < 3);

[download]

Example of usage: 

# consuming script: yourprogram.pl
use strict;
use warnings;
use Touchable;

print "here $0\n";

# usage example
perl yourprogram.pl 

# works only if touch activated..
touch yourprogram.pl & perl yourprogram.pl

here yourprogram.pl

Have a nice 1st of April!

Have fun!
