DictProperty Key Types?

[mikeholler]

Is there support (or plans for support) to specify key types for DictProperty? I'd like to enforce a dict of int to MyJsonObject and I don't see a way of doing that with the current APIs.

Would using an ObjectProperty solve this? https://github.com/dimagi/jsonobject/blob/master/test/tests.py#L42 That code ensures each Feature has hair and eyes
