Tragically, perl 5.18 requires a leading "use re 'eval'" if you embed the program in a regex. To appease this change in behavior, the Regex attribute now supports three different "true" values: 1: add a leading "use re 'eval';" for Perl 5.18+ only 2: do not add a leading "use re 'eval';" 3: add a leading "use re 'eval';"
