Hi. Some of the things you pointed out are very relevant and hence i've modified the script now. Note that this is not a module , its a package. I would like to keep the dimension of my script the way it is.
Packagtest.pl

package Packagetest;
BEGIN{
print"You are using Packagetest\n";
}

sub ReadFile 
{
    use strict;
    use warnings;
    my ($fn) = @_;
    open(my $fh, '<', $fn) || die "cannot read the file: $!";
    while (<$fh>) {
    chomp;
    my @tokens = split /\|/;
    print "Wrestlername: $tokens[0]\n";
    print "Crowdreaction: $tokens[1]\n";
    print "Specialmove: $tokens[2]\n\n";
    }
    
    }
return 1;
END{
    print"Thank you for using the package\n";
}

Here is the script that calls this package
TestPackage.pl

#!/usr/bin/perl -w
use strict;
use warnings;
require 'Packagetest.pl';
Packagetest::ReadFile("datafile");
