Language ReferenceA listing of experimental features in PerlDaftar Isi NAMEperlexperiment - A listing of experimental features in Perl DESCRIPTIONThis document lists the current and past experimental features in the perlcore. Although all of these are documented with their appropriate topics,this succinct listing gives you an overview and basic facts about theirstatus. So far I've merely tried to find and list the experimental features and infertheir inception, versions, etc. There's a lot of speculation here. Current experiments- fork() emulation

Accepted featuresThese features were so wildly successful and played so well with others thatwe decided to remove their experimental status and admit them as full, stablefeatures in the world of Perl, lavishing all the benefits and luxuries thereof. They are also awarded +5 Stability and +3 Charisma. Removed featuresThese features are no longer considered experimental and their functionalityhas disappeared. It's your own fault if you wrote production programs usingthese features after we explicitly told you not to (see perlpolicy).
