I notice that you have a mix of "object_" and "sol_object_" calls: are =
these all purely serialization functions (and should they all be =
prefixed with "sol_")? It would be unfortunate to commit to a stateful =
object *creation* API, as that would make things difficult for =
multithreaded work (e.g. each thread creates an object, each of which is =
added to the top-level object as it is completed rather than in lexical =
order).
