19:57:37Bikei see cando uses some custom bit vector functions. could probably straighten that up a little bit
19:58:00Bikee.g. SimpleBitVector_inPlaceOr is covered by core__sbv_bit_ior which i already wrote
20:09:07Bikeand there's lowestIndex which is find first set or whatever, and isZero, and ranged eq, all of those could be implemented without checking individual bits
