Huh. & might work, never tried it before;
The way I've got it set up Now is, it keeps an array of rooms that connect to other rooms; the array index is the room in question, the value at that index is a bitflag of which rooms it connects to (1 means 1, 2 means 2 and not 1, 3 means 2 and 1, 4 means 3, 5 means 3 and 1, etc). When it links two rooms it simply adds the values to combine the list of linked rooms, and then updates not just those 2 rooms but every room that links to those 2 rooms.

Moral of the story is, & might work for me, but it's not gonna make me happy; what, I have to revise every int(random(0,2)) now to have a special case for if it returns 2?!
