Package: vcftools
Version: 0.1.17-1
Severity: important
User: debian-perl@lists.debian.org
Usertags: perl-5.44-transition

The Vcf module in this package warns on usage with Perl 5.44 (currently in experimental.)

  $ perl -we 'use Vcf'
  Possible attempt to escape whitespace in qw() list at /usr/share/perl5/Vcf.pm line 2844.

The warning causes a debci regression, which is a blocker for a Perl 5.44
transition. There's an example debci log at

https://ci.debian.net/packages/v/vcftools/unstable/amd64/76870206/

If you want to test changes against Perl 5.44 in experimental and run
into uninstallability problems, there is a test repository of rebuilt
Debian sid packages for amd64 available at <https://perl.debian.net/>.

Hi,

I would love to help the Perl transistion.  It would help me a lot if
you could provide a patch - even pushing directly to Debian Med
repository + team upload (Debian Med team shares the same open
development model as Perl team) would be fine if this saves your time.

Kind regards
    Andreas.

Hi Andreas!

The following patch should do the trick to get rid of the above
warning with perl 5.44:
