Thanks for helping Manfred! However, as he noted, the documentation on
https://metacpan.org/module/File::Find::Object::Rule is misleading and ought to be corrected. Since
I've originated File::Find::Object::Rule (after forking it from the original
File::Find::Rule) and still maintain it, then I can do it now. So thanks to
Manfred as well for spotting this issue.
