Fellow Monasterians,

I'm discovering the benefits of reusable code. My question is this: do I have to put the code in a package or can it just be a file that ends with 1;? I have done it both ways, but the package method requires a little extra code. I have read in Programming Perl that the package method protects the namespaces, but what else? Thanks.

Main (without using package):

use Common.pm;
my $returnvalue = somesub();

Common.pm:

sub somesub {
    ...create value...
    return($value);
}
1;

Main (with package):

use Common.pm;
my $returnvalue = Common->somesub();

[download]

Common.pm:

package Common;
sub somesub {
    ...create value...
    return($value);
}
1;
