Dear Maintainer,

ply is a key package and is also turning python3-six in a key package.

https://release.debian.org/key-packages.html


Please at least tag python3-six as '<!nocheck>';
but maybe it's time to get rid of it altogether.

The one-line patch would look like this:
-from six.moves.queue import Empty
+from queue import Empty

Then python3-six can be dropped from debian/control & debian/tests/control

Greetings

Alexandre


$ grep six -r
