Hello Dagfinn,

Thank you for paying attention to it and improving the possible fix!

I reviewed my collection of unica I gathered for several months, but had
found some of them too minor/requiring more analysis.
Then I added more with perlcritic's policy UnusedVariables, and also
checked for unused subs with a script from blogs.perl.org (and it confirmed
my only previous find of that kind).

Yes, I saw unused $sqlstates, but decided that they are meaningful enough
to stay. Though maybe enabling ProhibitUnusedVariables justifies fixing
them too.

Agree, and I would leave 005_negotiate_encryption.pl (with $node_conf,
$server_config unused since d39a49c1e) aside for another day too.

Best regards,
