Hello choroba,

Yes, good point, I missed this. But warnings::unused installed for me (using cpanm) without problem, and seems to work as advertised. Whereas the CPAN Testers Matrix for Test::Vars shows that this suggested replacement module has not installed successfully on any platform since Perl version 5.21.7.

:-(
