The fact that tchrist's file-dir-perms doc is now relegated to a tarball in the olddoc tree does suggest that it is only kept for historical interest, despite the link from perlfaq5.

Good tidbit hippo! One more question, could you please tell me if that's also a mistake? From file-dir-perms:

What happens when you try to do this?

    perl -i.bak -pe 1 alpha/bar

Well, you seem to think you shouldn't be able to rename it because
it's mode 0555, readonly.  But that's irrelevant.  It's the diretory
that matters.  So it succeeds.

The previous command actually operates on alpha (0755) and on bar (0444). Why did he refer to beta (0555) here?
