Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
json-encode is supposed to return a JSON representation of its argument.
It fails on some objects:
(setq debug-on-error t)
(require 'json)
(json-encode (list (list 1)))
==> Debugger entered--Lisp error: (json-key-format 1)
(json-encode (list (cons (cons 'a 'b) 'a)))
==> Debugger entered--Lisp error: (wrong-type-argument listp a)
I understand that maybe not all objects make sense for json-encoding but
the documentation of json-encode does not specify what is a valid
argument, and (it seems) the package does not do it either.
Also the documentation does not list the error-codes so that we could
catch them in code.

I've now added some text to this function (and json-read) about what the
inputs, return values are and what error signals are raised to the Emacs
trunk.
