By always passing around a single, unnested array rather than splatting and then defensively flattening and compacting things, we can avoid allocating a bunch of unnecessary arrays. This gives a performance boost of roughly 4% when enumerating 2500 formulae, and has the side effect of cleaning up the dependency API.
