Does this happen just with bleadperl, or with older perls, too? I suspect this may be related to <https://rt.perl.org/rt3/Ticket/Display.html?id=123223>.

The tests are still/again failing here with version 2.39 on Perl 5.22.1 when PadWalker is not installed. The failure mode is # Can't locate object method "object_2svref" via package "B::PADNAME" at /home/niko/tmp/libdata-dump-streamer-perl/blib/lib/Data/Dump/Streamer.pm line 3708.

Do you think it would be ok to simply require Padwalker? Yves -- perl -Mre=debug -e "/just|another|perl|hacker/"

I confirm this happens on perl 5.22.1. Installing PadWalker made those test failures go away. Cheers!

Perhaps it needs a little explanation. Here is a new patch that contains some. It is git-am-compatible.
