Pushed 0001 with some changes of my own. I'm afraid I created a few
conflicts for the later patches in your series; please rebase.
I don't think we introduced anything that would fail on old Perls, but
let's see what buildfarm has to say.
Others: Now is the time to raise concerns related to the proposed file
formats and tooling, so please do have a look when you have a moment.
At this stage, the proposed data format seems a good choice to me.
Thanks
