I realized belatedly that my pseudocode doesn't really help in 
differentiating what I'm looking for from standard behavior (and the 
mailman issue had me worried that I had a bunch of RTFM replies waiting 
for me).  The labels /keys themselves are not related to the underlying 
DB and the values would be full SQL::Abstract criteria.  Actually, for 
now, disregard the whole question since I don't know whether it would be 
useful often enough to warrant (and it's easily enough done manually).
