PDL would be nice, but very much impractical to add to the core.

I think that, while existing modules should not be removed, the criteria for adding new modules to the core distribution should be fairly strict. Particularly, I would suggest limiting inclusion of new modules to either:

  1. Pure Perl modules that are both small and very widely used. If the majority of installations will be pulling a small module from CPAN, it might belong in core.

  2. Modules (usually XS, but some pragmata are pure Perl) that are intricately tied to the core and are effectively "optional builtins". If the module relies to a great extent on other support within the core, it should probably be shipped with the core. I believe that Scalar::Util::weaken and the restricted hash interface in Hash::Util are examples of features in this category. Another monk mentioned Hash::Util::FieldHash, which, as I understand, requires cooperation from the core garbage collector to do its work. It is therefore closely tied to the core and should probably be maintained with the core.

Or do I misunderstand the issue?
