Looks like all intersect, unite, and friends have serious flaws.
They have been posted on this list by some people, and I added them without
checking. Next time I will ;)
The functions themselves are not designed correctly, I would like to change
them from :

val intersect : t -> t -> unit

to :

val intersect : t -> t -> t

which will produce a new bitset. Sounds more logical to me in Ocaml world.
Any volunteer for implementation ?
Real Life takes quite a lot of my time too ;)
