The syntax for plain arrays is identical. I was suggesting JSON to manage
recursive data structures (nested solvers, perhaps monitoring different
things). So it becomes a dict of arrays or a dict of dicts of arrays. Also,
we could spit out -snes_view in machine-readable form, we could have nicer
diagnostics on the GUI side. It is because of these extensions that I think
it's worth starting with something that will extend gracefully rather than
a hack that is only intended for arrays of numbers.
