SDL_Perl

This distribution does not 'use strict;' (or its equivalents) in all of its modules. Note that this is not about the actual strictness of the modules. It's bad if nobody can tell whether the modules are strictly written or not, without reading the source code of your favorite clever module that actually enforces strictness. In other words, it's bad if someone feels the need to add 'use strict' to the modules.

Add 'use strict' to all modules, or convince us that your favorite module is well-known enough and people can easily see the modules are strictly written.

The documentation for this distribution contains syntactic errors in its POD. Note that this metric tests all .pl, .pm and .pod files, even if they are in t/. See 'pod_message' in the dist error view for more info.

Remove the POD errors. You can check for POD errors automatically by including Test::Pod to your test suite.

This distribution uses a module or a dist that's not listed as a prerequisite.

This distribution has .pm files with inconsistent versions.

Split the distribution, or fix the version numbers to make them consistent (use the highest version number to avoid version downgrade).

This distribution does not declare the minimum perl version in META.yml.

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.

This distribution does not 'use warnings;' in all of its modules. Note that this is not about that your modules actually warn when something bad happens. It's bad if nobody can tell if modules warns or not, without reading the source code of your favorite module that actually enforces warnings. In other words, it's bad if someone feels the need to add 'use warnings' to the modules.

Add 'use warnings' 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.

This distribution is not required by another distribution by another author.

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