Ahh, wisdom you seek. And some wisdom different from what you see here I can provide. You have a class Myclass yes?

use strict;
package Myclass;

sub foo { return 1; }

1;

Seeing the folly of your ways, you come to realize that the code must be

use strict;
package Myclass;

sub foo { return 42; }

1;
[download]

Search this program below for the answer

use strict;
use Myclass;

print "Foo is " . &Myclass::foo . "\n";
print "Modify the file and hit enter\n";
<STDIN>;
do 'Myclass.pm';
print "Foo is " . &Myclass::foo . "\n";

And thus does "do". But note, that if we delete foo, the function remains in the symbol table, and thus stays. A more through approach would clobber the table elements from the package. Class variables are vulnerable as well. And use warnings will warn.

In your service,
