I've look at it, and it seem it's an implementation of a set, not of a
map. So if one want a map, he have to use a weak hashtable of
couple. But if he want the couple to be alive when ever say its first
element is alive, one have to make the couple accessible from the
first element. So to say the least, it's difficult to use it like
this. 

By the way, I'm not sure to think of a good solution for this.
