"""Priority based json library imports.

Always serializes to bytes instead of unicode for zeromq compatibility
on Python 2 and 3.

Use ``jsonapi.loads()`` and ``jsonapi.dumps()`` for guaranteed symmetry.

Priority: ``simplejson`` > ``jsonlib2`` > stdlib ``json``

``jsonapi.loads/dumps`` provide kwarg-compatibility with stdlib json.

``jsonapi.jsonmod`` will be the module of the actual underlying implementation.
