I've recieved approval to release the JSON library for Erlang!
I'll get it cleaned up and released tomorrow.

I've pondered that.  It's a little awkward with the quoting and
unquoting you need to do.  Binaries also imply that you'd need to
choose a Unicode format for the internal representation that would
be good for all applications.

Yeah - I'd be glad to trade the asymptotic efficiency of dicts for
compactness and nicer printing.  I liked dicts until they started
showing up in error reports.  I'll probably change this in a future
release.

Pattern matching?  This means you'd have to:

	* have the JSON decoder always sort the assoc-list;
	* remember to maintain your pattern assoc-list in sorted order;
	* have optional fields sort after mandatory fields.

Am I forgetting some new language feature?

Thanks for your thoughts!
