But that's only two levels, when the number of levels
can really be unbounded.  Only the *top* level can be
a list, rather than an array.

Since any two levels can have a relationship
        ...->[0]->[0]->...
        ...->[0]->{X}->...
        ...->{X}->[0]->...
        ...->{X}->{X}->...
that calls for AoA, AoH, HoA, HoH.
