 Previously, if one embeds Perl or uses XS and calls fork(3) from C, Perls
 notion of C<$$> could go out of sync with what getpid() returns. By always
 fetching the value of C<$$> via getpid(), this potential bug is eliminated.
-Code that depends on the caching behavior will break.  As describe in L</Core
-Enhancements>, C<$$> is now writeable, but it will be reset during a fork.

+Perl skips copying values returned from a subroutine if it thinks the value
+is not in use elsewhere.  Due to faulty logic, this would happen with the
+result of C<delete>, C<shift> or C<splice>, even if the result was
+referenced elsewhere.  So C<< \sub { delete $_[0] }->($x) >> would return a
+reference to C<$x>.  This has been fixed [RT #81944].
