lintian use warnings FATAL => 'all' check?
A few perl 5.22 FTBFS bugs were caused by a new deprecation warning
together with use warnings FATAL => 'all'. This problem is eloquently
described at , which suggests not using this pragma form.
This looks like an ideal case for a lintian warning. Because it's
somewhat controversial, we'd probably want to start gently, with a
low severity warning, and with careful wording (particularly around
advice for what to do instead).
I'm not able to put any time into this in the near future - would
anyone else be interested in taking this on with a wishlist bug/patch
to Lintian, or views about the merits of this idea?
