For a specific example, I haven't the faintest intuition about what 'map' should do. Suppose we have {(k1)x1, (k2)x2} and f x1 == f x2 = y. Should the value of map f {...} be {(k1+k2)y} or {(k1`max`k2)y} or what?
Good question. I'd suppose that they should be parametrized by any (Abelian?) group on the weights/multiplicities, where (+) is the canonical one since we're talking about "negative" membership. Though it'd be nice to get clarification, and to actually have the group/etc be a parameter (i.e., by type class constraint) rather than hard-coded into the structure. -- Live well, ~wren
