"preceding" and "following" are purely spatial.  It has some,
mmm... interesting applications.  Look at this example that I still
think is my greatest Lout hack (with-plug :shameless  As Jeff said,
"I just hope that Lout is up to it". ;)

As I wrote on several occasions, I think that the spatial aspect of
Lout is under-appreciated if clearly understood at all (my mind just
boggles and gets a watchdog reset when I think about it).

Well, you need to pair your Qs and As somehow.  You can do it
spatially, by feeding them in pairs in the sorted order Q1 A1 Q2 A2 -
which is the most simple solution.  Or you can (I think) pair them
using tags.  The latter, if possible, will have a hard performance
hit, as the whole list (i.e. the whole document) will need to be held
in the memory.
