check_type() checks the array's contents, then peels off the array and
falls through to the "not array" code without resetting allow_array
and allow_dict to False.  Works because the peeled value is a string,
and allow_array and allow_dict aren't used then.  Tidy up anyway:
recurse instead, defaulting allow_array and allow_dict to False.
