+Deprecated modules and features are those which were part of a stable

+They are subject to removal and/or bug-incompatible reimplementation in

+=item (to be) dropped modules
+
+When Perl 5 was first released (see L<perlhistory>), several modules were
+included, which have now fallen out of common use.  It has been suggested
+that these modules should be removed, since the distribution became rather
+large, and the common criterion for new module additions is now limited to
+modules that help to build, test, and extend perl itself.  Furthermore,
+the CPAN (which didn't exist at the time of Perl 5.0) can become the new
+home of dropped modules. Dropping modules is currently not an option, but
+further developments may clear the last barriers.
