Well, I was mostly curious if it encoded some transfer of wisdom among
mnesia hackers. A secret language that say something without using
comments?

I'm just trying to orient myself in the codebase to see if it is
possible to query an index for record's primary keys only. To allow me
to use several such primary key lists and perform set intersections to
implement an SQLish
"... WHERE A = 1 AND B = 2", only looking up the primary keys in the
intersection so less records are involved.
