Counting Lines of Code: Rules

        unless ($page->param('round')) {        # 1
           $round = 0;                          # 2
        }else {
           $round = $page->param('round');      # 3
        }

        unless ($page->param('round')) { $round = 0 }   # 1-2
        else { $round = $page->param('round') }         # 3

Basic principle: Items with new semantic content count; others do not
White space does not count
Each simple statement counts for 1
Control clauses such as while, if, etc. count for 1
do and else don't count
Don't worry too much about details
