All,
I am currently writing an network application that requires the ability to modify the running code without dropping connected users. I have already split the package across several files. This makes maintenance easier as well as allows for parts of the code to be re-loaded individually. Here is an example:

Script that uses the module 

#!/usr/bin/perl
use strict;
use warnings;
use Cool;

my $obj = Cool->new();
while (1) {
    print $obj->testit(), "\n";
    sleep 1;
    $obj->soft_boot();
}

[download]

The module itself 

package Cool;
use strict;
use warnings;

require 'magic';
'This statement is false';

[download]

The file called 'magic' 

package Cool;
use strict;
use warnings;
no warnings 'redefine';

sub new { return bless {}, $_[0]; }
sub testit { return 'Change me and see what happens'; }
sub soft_boot { do 'magic'; }

'This statement is false';

[download]

Given this bizarre situation, is this the sanest way you can think to do it? If not, please offer your advice (preferrably with a working code snippet).

And yes diotalevi, I know this blows my method cache

Cheers - L~R
