I'd vote for modify compare.pl into compare.pm. Actually I'd copy compare.pl to Compare.pm and add:

package Compare;

# modified original contents of compare.pl here

1;

The package line at the top and the (implicit return) 1 at the end are pretty much all the extra stuff you need. In your calling script you:

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

...
Compare::SomeSubInTheCompareModule ();

[download]

Notice the way sub SomeSubInTheCompareModule is called by using the package name. Aside from that icing a sub in Compare is called and used in just the same way as a sub in the .pl file.

True laziness is hard work
