Doesn't that pretty much cover it? > I agree with Merlin that 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: json_typeof() NOT IN ('object', 'array') json_typeof() IN ('string', 'number', 'boolean', 'null') And it protects the user against forgetting about, say, the 'null' typeof() when constructing their check expression.
