[Pharo-users] BitField

[abdelghani ALIDRA]

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?
