Hello, You maybe can use Integers as bitfield: bitField := 0 bitAt: 200 put: 1. executing bitField bitAt: 200 will return 1. The only thing to take care is that it # bitAt:put does not change the object itself, but instead returns a new one. Marcus

Hi everybody,
I was discussing with Thibault about the performance of some methods defined on sets ( actually quite slow for big collections, mainly union: and intersection: ) and we were wondering if there is any implementation of some BitField-like class to speed up these operations? May be in an external project?
