The refusals: the arities, a pool of an owning element, ordering handles, free of a handle, and clone of a pool. Each names what it would cost — a cloned pool duplicates the generation counters with the slots, so one handle would resolve in both copies and name two different things. pool-stale-region.flan is the other failure, and the point of it is that it is not the first. A stale handle is an answer and resolve says None; a pool whose region was released has no slot array left to ask, so it traps. Same rule that keeps a Vec's generation word and its epoch word apart.
