Chill also has/had 'bitstrings' and 'powersets' (i.e. what Pascal calls 
'sets'), both of which are basically bit-pached arrays of booleans.
The latter uses the SET_TYPE tree code, and we added some support in
store_constructor and a couple of other places, but mostly we just
generated function calls.  Real back-end support would have made it
easier to generate better code.
