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.
