      Description

      The implementation can be refactored, and also there has been a note in the code since this class was created suggesting that additional optimizations may be implemented. The optimizations fall into two categories:

      • some btree skips that are applied for range bounds may be optimized out for $in bounds (in some cases they are already optimized out)
      • in some cases fewer comparisons could be performed by the implementation
