Dictionary payload with numeric keys become strings

[baubie]

Happens using Serializer and URLSafeSerializer:

>>> s.loads(s.dumps({1: 2}))
{'1': 2}

I don't think this should be intended behaviour -- using version 0.24 with Python 3.5.

Cannot be avoided when using a json serializer. JSON keys are always strings...

You can use a different internal serializer, such as custom JSON that converts a dict to a list of key, value pairs, or YAML. Pass serializer= when instantiating the serializer (confusingly named, yes). https://pythonhosted.org/itsdangerous/#itsdangerous.Serializer This isn't something that will be changed in the library though.
