trailing text is returned as 3rd return value. (The 3rd return value is
always there, but with ``trail`` set, no error is raised.)
``utils.format_json(v)``
Format the given Lua table (or value) as a JSON string and return it. On
error, returns ``nil, error``. (Errors usually only happen on value types

``utils.to_string(v)``
Turn the given value into a string. Formats tables and their contents. This
doesn't do anything special; it is only needed because Lua is terrible.
