I used the "|" as regex delimiter, to avoid the "leaning toothpicks" syndrome - ie to avoid having to escape the "/".

But doing that to avoid LTS puts you in danger of succumbing to STD (Straight Toothpick Distemper) the first time you use an  | alternation in your regex. Why not just use a pair of nesting delimiters,  { } for e.g., and be immunized against many of these pathologies? 

$s =~ m{ (\d{1,2}) / (\d{1,2}) / (\d{1,2}) }xmsg
