-=head2 Subroutines no longer need typeglobs
-
-Perl 5.22.0 introduced an optimization allowing subroutines to be stored in
-packages as simple sub refs, not requiring a full typeglob (thus
-potentially saving large amounts of memory).  However, the optimization
-was flawed: it only applied to the main package.
-
-This optimization has now been extended to all packages.  This may break
-compatibility with introspection code that looks inside stashes and expects
-everything in them to be a typeglob.
-
-When this optimization happens, the typeglob still notionally exists, so
-accessing it will cause the stash entry to be upgraded to a typeglob.  The
-optimization does not apply to XSUBs or exported subroutines, and calling a
-method will undo it, since method calls cache things in typeglobs.
