News and updates

   Dave Mitchell [1]merged the signature optimizations branch he was working
   on. Exciting!

   Todd Rinaldo [2]suggested (Smoke-It branch?) introducing smoking of perl
   core branches against CPAN to test how specific features affect CPAN and
   might cause breakage. More about that further down under Discussion.

   A new version of [3]Encode (2.84) is [4]out.

   directory, which is not advised.

   Karen Etheridge provided a patch to [35]Perl #128836 ([36]XSLoader meta
   information incorrect) which was merged.

Discussion

   Under [37]Perl #126310 (no "Malformed UTF-8 character" warning on
   single-quoted strings under use utf8), Karl Williamson and Father
   Chrysostomos discuss where in the code to solve the issue.

   Karl Williamson [38]mentioned (Re: ASCII support in z/OS) that there
might
   be a way to support ASCII in z/OS without breakage to those not using
   ASCII-based z/OS instances.

   Father Chrysostomos [39]asked (Alignment question) about alignment of the
   parser struct. There are additional comments from Leon Timmermans, Eric
   Wong, and Tony Cook, providing details on the issue.

   Todd Rinaldo [40]intends ([perl #127810] Provide -Dfortify_inc Configure
   option to remove .from @INC) to submit a rebased patch. Craig A. Berry
   [41]recommended picking a name which is more descriptive and not
absolute,
   so people will not assume a wider range of issues were addressed by this
   change.

   As mentioned above, Todd suggested a way to smoke perl branches against
   CPAN to detect breakage. Andreas Koenig [42]provided his recipe for doing
   this, which he uses to help test breakages of CPAN for specific features.

   Dave Mitchell [43]confirmed that [44]Coro 6.511 builds successfully on
   Linux with ithreaded DEBUGGING perl 5.22.3-RC2.

   James E. Keenan [45]updated about test failures in blead, which Karl
   Williamson confirms is on Linux and found the offending commit. Father
   Chrysostomos provides a fix.

   Father Chrysostomos [46]asked about an optimization he had done and
   wonders if he's interpreting the output of cachegrind correctly and
   whether the change is valuable.

   Karl Williamson [47]suggested (RFC: perldeprecated.pod) adding a pod to
   list deprecated features, and possibly those that are discouraged,
   including the time they fell under this category and when it is scheduled
   to be removed.

   Yaroslav Kuzmin [48]provided (Re: ASCII support in z/OS) a response
   regarding ASCII support in z/OS. Yaroslav also [49]summarized the
   different options available.

   Dave Mitchell [50]provided (Re: Interpreting cachegrind output)
   explanations on how to measure performance differences in perl.

   Michael Schroeder [51]asked about a different way to handle a recent
   change in [52]base.pm.

   Jim E. Keenan [53]asked (Internals:: undocumented) about the Internals::
   namespace and its documentation. It is undocumented and should not be
used
   by any non-core module.
