The new P5P summarizer is Scott Lanning. Read on for his latest summary, which is, in fact, his second one. In order to catch up with the Perl 5 development, he also wrote a summary for the month of September.
Andy Lester reported (bug #31730) that $fh->getline on a directory sometimes returned garbage and other times undef. Steve Peters pointed out that it depends on which OS you're on, which H. Merijn Brand demonstrated on several systems. People blahed at the idea of an argument to IO::File->new to specify the behavior of reading from a directory, though a note in the docs might be okay.

Ton Hospel needed an equivalent of eval {} for XS code but didn't find any such thing in the API doc or perl source code, so he made his own. Nick Ing-Simmons explained how in Tk he does eval { &foo } by making a CV for the contents of {} then calling call_sv(cv, G_EVAL). (Note: examine btkGlue.c -- Lang_catch, Tcl_GetRegExpFromObj, and do_comp).

Nobody knows apparently, even at perlmonks. He tried not clearing IoIFP,
but it caused a test to break.

Tels was doing a require Carp instead of use Carp in order to load
it on demand, but then found that use vars does use warnings which
in turn does use Carp! So he submitted a patch for warnings. Then
Vadim Konovalov noted how he always optimizes Dynaloader locally,
so he also submitted a patch.

Abe Timmerman, with Craig Berry's help, tried building bleadperl (on porting Test::Smoke) on OpenVMS -- on a VAX. It seems there are problems with 8-level directory names like
DISK$USER_2:[TIMMERMAN.KLAD.PERL-CURRENT.LIB.AUTO.FILTER.UTIL.CALL]
If that didn't trigger your VMS allergies, you might try the rest of the thread:

Chris Kelly was vivified enough to report that
open $1, $file or die;
doesn't die. Dave Mitchell fixed it by making open croak if the first argument is read-only.

perl@pythontech.co.uk found (bug #31767) that printing from an undef variable prints out junk instead of nothing in perl 5.8.3:
$data = "13 characters"; $data = undef;
open(MEM, '<', \$data) or die "Fail: $!\n";
while (<MEM>) { print }
Rafael Garcia-Suarez fixed this in the development branch.

Zefram (bug #31793) found that use overload wouldn't work when setting
the $Data::Dumper::Useqq variable. Rick Delaney provided a patch to fix
overload.pm (with Tels independently arriving at the same conclusion,
apparently).

Craig Berry made at least two VMS test fixes:
