You should not be sorry. Even if the topic seems trivial and elementary, it turned out to be more complex than one would probably think, and thus the discussion has been very interesting.
BTW: to insert a link you should use [id://527973] or [id://527973|here], which render like Perl Idioms Explained - my $count = () = /.../g and here respectively. This is the preferred way since they will bring up the correct link both if you're in http://perlmonks.org and http://www.perlmonks.org, or any other possible mirror. See this node for more info.
