Kwalitee Issues


Add a META.yml to the distribution. Your buildtool should be able to autogenerate it.


Add a META.json to the distribution. Your buildtool should be able to autogenerate it.


Define the license if you are using in Build.PL. If you are using MakeMaker (Makefile.PL) you should upgrade to ExtUtils::MakeMaker version 6.31.


Fix the version numbers so that version::is_lax($version) returns true.

Add 'use warnings' (or its equivalents) to all modules (this will require perl > 5.6), or convince us that your favorite module is well-known enough and people can easily see the modules warn when something bad happens.

Error: Persistent::Base, Persistent::DBM, Persistent::DataType::Base, Persistent::DataType::Char, Persistent::DataType::DateTime, Persistent::DataType::Number, Persistent::DataType::String, Persistent::DataType::VarChar, Persistent::File, Persistent::Memory


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