Some remarks:

links

It would be easier for all of us if you linked to those perldocs.

That's quite easy, just edit your post and and run a regex to surround each missing command with [doc://...]

like atan2 -> atan2

grouping

The next point is classification

getservbyname and many others belongs to the group Fetching-network-info

Assembling the commands in such groups would facilitate the task a lot !!!

They were originally classified in the perlfunc you copied, why did you strip it again?

Compare "divide and conquer"

snippets

Next: After reading Re^2: How to find Perl demo programs? I assume you rather mean usage snippets than full demo programs.

It would be very nice to have such snippets for many reasons.

• IDEs could profit from suggesting them
• The behavior of Perl is often underdefined
• The docs are often overly complex, the main info get lost in sometimes cryptic mentions of edge cases.
• Perl is undertested, such snippets could be used to catch regressions from version to version

I once tried an automatic approach to generate them, but alas life came in-between.
