Empty lock files certainly aren't wrong either. MJD's talk discusses how many problems can be solved by using a lockfile that is different from the target working files. And that's what you're doing. I mostly just didn't want someone seeing open my $fh, '>', ...; and then flock, and think this idiom will translate well to locking an output file that they intend to write to.

    Yeah, I have to make that clear to my colleagues. My concern was the warning in the docs that locking might fail if the lock-file is not opened for writing.

    And the side effects on Win are giving me a hard time when following recipes born on Linux.

    Thanks for sharing those links! :)
