+=item deprecated modules and features
+
+Deprecated modules and features are those which were part of a stable
+release, but later found to be subtly flawed, and which should be avoided.
+They are subject to removal and/or bug-incompatible reimplementation in
+the next major release (but they will be preserved through maintainance
+releases). Deprecation warnings are issued under B<-w> or C<use
+diagnostics>, and notices are found in L<perldelta>s, as well as various
+other PODs. Coding practices that misuse features, such as C<my $foo if
+0>, can also be deprecated.

+=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 by the time of Perl 5.0) can become a new
+home dropped modules. Dropping modules is currently not an option, but
+further developments may clear the last barriers.
