+=head1 NAME
+
+perlexperiment - A listing of experimental features in Perl
+
+=head1 DESCRIPTION
+
+This document lists the current and past experimental features in the perl
+core. Although each 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, etc versions. There's a lot of speculation here.

+=head2 Accepted features
+
+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.

+=head2 Removed features
+
+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 L<perlpolicy>).
