| Subject: | Failed test on perl 5.20.2 |
A simple test. This may be a bug in the interaction between Unknown::Values and new $Data::Dumper::Useperl semantics.
$ ~/tmp/isas/perl5.20.2/opt/IBM/mibe/perl/bin/perl -Ilib -MData::Dumper -E 'package Data::Dumper; use Unknown::Values; $Useperl = 1; say Dumper([unknown])'
Dereferencing cannot be performed on unknown values at lib/Unknown/Values/Instance.pm line 55.

Which is fine. Except that this is also done inside Test::Differences, which is called by Unknown::Values' test suite, and I get the following output:
$ ~/tmp/isas/perl5.20.2/opt/IBM/mibe/perl/bin/perl -Ilib t/basic.t
ok 1 - Direct comparisons to unknown should fail (==)
ok 2 - ... and unknown should not be == to itself
ok 3 - ... and unknown should not be eq to itself
ok 4 - Direct comparisons to unknown should fail (<=)
ok 5 - Direct comparisons to unknown should fail (>=)
ok 6 - Direct comparisons to unknown should fail (>)
ok 7 - Direct comparisons to unknown should fail (<)
ok 8 - Direct negative comparisons to unknown should fail (!=)
ok 9 - Direct negative comparisons to unknown should fail (ne)
ok 10 - Negative comparisons of unknown to unknown should fail (ne)
ok 11 - unknown values are not returned with <
ok 12 - unknown values are not returned with >
