Replace dir_size with a test sub that prints the param that is parsed in to it. dir_size really shouldn't care how it is called so there must be some difference in what is being passed in. A suitable test sub would be sub test {my $param = shift; print "param: >$param<\n";}

Perl is Huffman encoded by design.
