# I guess what you're looking for are sorted arrays:
#   1) O(log n) lookup and insertion via binary search
#   2) O(n) union and intersection are simple
#   3) Equal sets are represented by structurally equivalent objects.

Hmm, except that, if I'm not wrong, it was required the structure to
hold any kind of object. Sorted arrays require the elements to be
sortable. Using the hash of the objects may be an answer ?
