This Week on perl5-porters was started by Mark-Jason Dominus five years ago on October 17, exactly five years after the release of perl 5.000.
Richard Foley and Yitzchak Scott-Thoennes added support for debugging
programs using ithreads. This added the e and E commands for
displaying the current thread ID and list of thread IDs, respectively,
when -dt is specified on the command-line or $ENV{PERL5DB_THREADED}
is set.

Steve Hay wondered what Perl source code filters should do on failure.
Perl isn't aware that there was a failure, so it's necessary to croak
from the filter. A Perl_filter_read comment suggests that it should
return a negative number on failure, whereas S_filter_gets just
returns null, so it's not clear which should be correct.

Nicholas Clark found a problem (#31924) in bleadperl:
$ echo die >fail.pm $./perl -Ilib -e 'eval "use fail q{:std};"; $INC{"fail.pm"} = "fail.pm"' Modification of non-creatable hash value attempted, subscript "fail.pm" at -e line 1.
Rick Delaney said this is because of compile failures being cached wrongly,
and he submitted a patch to make keys %INC only return names of files
successfully loaded. Yitzchak Scott-Thoennes objected to having hidden
entries in %INC.

David Radunz offered a patch to Exporter so that it would declare constants.
Michael Schwern fears that this will make Exporter much slower and that
it might not be that useful anyway because not all constants are declared
with constant.pm.

David Wheeler proposed having Pod::Man force uppercasing of =head1
headings. Russ Allbery resisted this, because Pod::Man doesn't
necessarily only generate regular man pages, though he'd be open
to an option.

Nicholas Clark mentioned that he plans to go to a four month release schedule (previously it was three months), which means a code freeze on Halloween for 5.8.6.

Craig Berry fixed a Devel::PPPort test on VMS.
Moshe Kaminsky fixed warnings::warn($obj, $msg) where $obj has
overloaded stringification.
Tels made warnings.pm not load Carp.pm unnecessarily, saving a bit
of memory.
