+Versioning is required. Primitives, excluding ``bytes``, can be returned as
can dicts. Again ``dict`` values do not need to be serialized,

registered serializer, take special care
not to have circular imports. Typically, this can be avoided by using ``str``
for populating the list of serializers.
Like so: ``serializers = ["my.company.Foo"]`` instead of ``serializers =
[Foo]``.
