Questions tagged [perl5.8]

perl5.8 refers to questions about that particular version of Perl. Perl 5.8 is officially unsupported.

Perl v5.8 was the longest lived version of Perl. It was released on July 2002, and the last version was released on December 2008.

Since then, Perl has been adding new features which won't work on this version. People stuck on this old version won't be able to use some of the answers that use features from a supported version of Perl.

Can I make sure Perl code written on 5.10+ will run on 5.8?

Some of the new features of Perl 5.10 and 5.12, such as "say", are defined as features, that you can enable or disallow explicitly using the "feature" pragma. But other additions, like the named capture groups of regexes, are implicit. When I write…
