There is no "I wrote this on 5.10.1 so I can't be sure it will work on other versions" feature.

There can only be such a feature if sufficient numbers of Perl 5 programmers stop pretending that perl is completely forward and backwards compatible without explicitly including version numbers in all files.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
