Just to poke my head in again -- AFAIK, Burton et al. were using heterogeneous 
value lists of 10,000 elements (multi-day compile times, but really fast 
code...).

Again, I'd like to refer to the heterogeneous value lists used by Burton et 
al. Their use of larger heterogeneous value lists syntactically favors type 
vectors. I explained their approach in the thread "Potential use for multiple 
sequence types".
