json_is_object()is superfluous, since it can just be replaced with json_typeof() = 'object'.  Likewise for
json_is_array(). But without json_is_scalar(), the choice is one of these two forms:<br /></div><div
class="gmail_extra"> json_typeof() NOT IN ('object', 'array')<br /></div><div class="gmail_extra">  json_typeof() IN
