Jean-Philippe Paradis makes an astute observation:
.@PuercoPop After XML→JSON, next step is JSON→sexp. There'll be unnecessary intermediary steps but the world's asymptotically getting there.

For some time, I’ve recommended JSON because it’s a sort of lingua franca that’s available to you no matter what language you’re writing in. Nevertheless, I’ve always felt that s-expressions are the better answer. If Paradis is correct, we will have the best of all worlds.
