perlexperiment - A listing of experimental features in Perl
This document lists the current and past experimental features in the perl core. Although all of these are documented with their appropriate topics, this succinct listing gives you an overview and basic facts about their status.
So far I've merely tried to find and list the experimental features and infer their inception, versions, etc. There's a lot of speculation here.

These features were so wildly successful and played so well with others that we decided to remove their experimental status and admit them as full, stable features in the world of Perl, lavishing all the benefits and luxuries thereof. They are also awarded +5 Stability and +3 Charisma.
These features are no longer considered experimental and their functionality has disappeared. It's your own fault if you wrote production programs using these features after we explicitly told you not to (see perlpolicy).
legacy
The experimental legacy pragma was swallowed by the feature pragma.
