| Subject: | missing_build_prereqs, missing_prereqs omits mentioning core and dual-lifed modules |
It looks like these metrics do not look for missing declarations of modules that are in core.
Note that not everything in core is *always* in core; e.g. Scalar::Util wasn't core in perl 5.6, so every distribution using it that claims to work on perl 5.6 should list it in prereqs. Also, modules can be removed from core, such as Module::Build no longer being in 5.21.0 and up.
I would recommend at least requiring dual-lifed modules to be listed. (I am working on an interface in Module::CoreList to make this query easier, as it's not an easy question to answer right now.)
