That's why I had resigned myself to resorting to looking up the toc.

Yes, now that you mention it, that's what I had forgotten, that's why
I had given up on referencing: the depending refs, the disaster that
follows when the stuff I want to refer to moves from this section to
that section.

I think I am doomed again to no reference or do the referencing at
the very end. Still, automatic labeling of ALL sections would still
be useful at that stage.
