+=head1 NAME
+
+Perl::Critic::Policy::Subroutines::ProhibitNestedSubs - C<sub never { sub correct {} }>.
+
+=head1 AFFILIATION
+
+This Policy is part of the core L<Perl::Critic> distribution.
+
+
+=head1 DESCRIPTION
+
+B<Attention would-be clever Perl writers (including Younger RJBS):>
+
+This does not do what you think:
+
+  sub do_something {
+      ...
+      sub do_subprocess {
+          ...
+      }
+      ...
+  }
+
+C<do_subprocess()> is global, despite where it is declared.
+Either write your subs without nesting or use anonymous code
+references.
+
+
+
+=head1 CONFIGURATION
+
+This Policy is not configurable except for the standard options.
+
+
+=head1 NOTE
+
+Originally part of L<Perl::Critic::Tics>.
