-=head1 NAME
-
-perlexperiment - A listing of experimental features in Perl

-=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
