If you are using Build.PL define the {requires}{perl} = VERSION field. If you are using MakeMaker (Makefile.PL) you should upgrade ExtUtils::MakeMaker to 6.48 and use MIN_PERL_VERSION parameter. Perl::MinimumVersion can help you determine which version of Perl your module needs.

Add 'use warnings' (or its equivalents) to all modules, or convince us that your favorite module is well-known enough and people can easily see the modules warn when something bad happens.

Error: Data::Workflow, Data::Workflow::BFSort, Data::Workflow::GraphAlgorithms, Data::Workflow::Log, Data::Workflow::Log::Object, Data::Workflow::Namespace, Data::Workflow::Namespace::database, Data::Workflow::Namespace::null, Data::Workflow::Namespace::path, Data::Workflow::Namespace::uri, Data::Workflow::Resource, Data::Workflow::ResourcePool, Data::Workflow::Step, Data::Workflow::Step::cat, Data::Workflow::Step::copy, Data::Workflow::Step::copy::Operation, Data::Workflow::Step::database, Data::Workflow::Step::database::append, Data::Workflow::Step::database::create, Data::Workflow::Step::database::create_schema, Data::Workflow::Step::grep, Data::Workflow::Step::perl, Data::Workflow::Step::touch, Data::Workflow::Step::untar, Data::Workflow::Util, Data::Workflow::Version, Data::Workflow::VersionMap

Add a 'repository' resource to the META.yml via 'meta_add' accessor (for Module::Build) or META_ADD parameter (for ExtUtils::MakeMaker).

This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.
