About Perl documentation...
...perldocs are rather flat and should be IMHO better displayed with "woman.el" (man doesn't work on windows).
Update: I've just pushed a cperl-mode where M-x cperl-perldoc just works on Windows. I didn't find woman.el particularly rewarding, though, and I took a different route. On the plus side, hyperlinks in POD files now work, and are resolved in your local installation (unless they are https links). Many perldoc pages are flat, but others like the Moose::Cookbook make more fun when links work.
Other documentation functions of cperl-mode will also be made available on Windows, as my time permits.
The code is at cperl-mode.el on GitHub, there's also a List of changes.
I've also completed the FSF paperwork, so there are chances that some changes will make their way into the official Emacs distribution.
