We've been talking about doing type-specialized storage for indexed array properties, and I have a patch that tracks some statistics about where we see same-type arrays (at finalization time, so there is some noise in the signal).
Second column is number of arrays, third is summed number of entries (dense). Running all of the ss tests gives:
array type meter (0x282000):
all int: 31428 138580
all dbl: 18097 105163
all str: 16027 117386
all obj: 2737 14847
(other): 1222 153627

I guess this was as instrumented as it needed to get!
