Hello, tobyink.

Thanks for taking the time to suggest a list of "Must Have's"!

I really appreciate your input. As I'd be inclined to think your activity on the CPAN (~tobyink) to provide, perhaps, more insight to the Must-Have's. :)

As to:

In practice there are quite a few modules which are only available as part of the core Perl distribution, and are not on CPAN in their own right. This means that if you cut them out of your Perl install, users cannot obtain them from CPAN. So you probably need to keep them.

This one is a Moving Target (see my comment in your Re: Perl 5.20.0, and perl What is new for perl v5.20.0) for greater context. As a possible remedy; it seems worthwhile to/for someone to maintain such "depreciated", not-included, or CORE-only modules. Which also speaks to your suggestion for including CPAN-enabling Modules.

Thanks again, tobyink, for taking the time to compile a list of Must-Have's. Greatly appreciated.
