Corrections

   The previous summary contained an incorrect link in the last paragraph
   which led to a 404. Thank you, Tony Cook, Ben Bullock, and Choroba, for
   spotting it.

News and updates

   Grant reports from Dave Mitchell [1]available. Due to a vacation, few
   hours were used this week.

   Dave also provides his monthly grant [2]report.

   Additional grant reports from Tony Cook [3]here, [4]here, and [5]here.

   In total, about 52 hours and approximately 38 tickets were reviewed or
   worked on, and 7 patches were applied.

   Tony also provides his [6]monthly grant report for January 2016.
   Approximately 43 tickets were reviews, and 11 patches were applied.

   Ricardo Signes [7]announced that [8]Time::HiRes is now upstream-blead.

   Ricardo Signes is hoping to [9]find more release managers for perl
5.25.x.

   Karl Williamson [10]updated that the Unicode Consortium has accepted
5 new
   emoji characters for Unicode 10.0.

   Ricardo Signes has [11]announced an upcoming code freeze. February 20th
   will be another development release and the user-visible code freeze. All
   additional changes, apart from pending bug fixes, should go through the
   list.

   In preparations for perl 5.24, Ricardo [12]started a review of all 5.24
   blocking tickets.

Proposed patches

   Tony Cook [42]submitted an updated patch and worked with Felipe Gasper on
   the best phrasing for documentation in [43]Perl #127386.

   Tony also provided a patch for [44]Perl #125833 (leading semicolons in
   require).

   James E Keenan provided a patch for the documentation of pos in [45]Perl
   #127518.

   Bulk88 provides a patch in [46]Perl #127532 to fix Win32 gmake with Win64
   VC with 32 bit GCC in PATH build failure.

   Tom Hukins provides a patch in [47]Perl #127533 to fix tests in a FreeBSD
   jail.

Discussion

   Ricardo Signes has [48]asked for more clarifications about the suggested
   change in [49]Perl #127384, making [50]Exporter to use [51]Importer for
   additional features.

   Chad Granum [52]adds more information on it.

   Jim Avera [53]adds more information on how important fatal warnings are,
   relating to [54]Perl #127323, asking to have fatal warnings collect all
   fatal warnings during compilation and not halt on the first one.

   [55]Perl #126414 (perl rounds inode in PP stat) is an interesting
scenario
   of "this shouldn't work but does". Bulk88 and Aristotle Pagaltzis have a
   [56]subthread with more details.

   Kent Fredric [57]requests anyone that objects to tainted hash keys in
core
   to provide proof that it is unacceptable.

   James E. Keenan seeks for more information relating to
gethostabyname() in
   [58]Perl #127519. Paul Evans [59]adds information on how the resolving
   interface works.

   Ricardo Signes opened [60]Perl #127531 to discuss a nicer, possibly more
   obvious syntax for variable aliasing by reference:

 my \@y = $x;

   (It is currently \my @y = $x.)

   Vadim Konovalov asked about the behavior of [61]strict regarding a change
   made to verify it was loaded as strict.pm (or strict.pmc), in order to
   prevent use Strict; silently being a no-op on case insensitive
   filesystems. This caused a failure in a hand-crafted fatpacker Vadim has
   written because of the value of __FILE__ (being used in the verification
   code of [62]strict).

   The solution includes using the line tracking abilities of Perl, such as
   #line 1 "strict.pm" to set __FILE__ in evaled code.
