serialize individual args/kwargs rather than the containers
This allows specials to be handled inside containers as args/kwargs
It is less efficient than before (still more efficient than 0.13) in cases where there is a very large number of simple arguments, but I think that generally the number of arguments is modest, and simple cases of small containers of arrays/References are likely (as most readily demonstrated by use in map).
The relevant behaviors are tested.
