Can't register a forward reference as a deserializer

[mjpieters]

Unfortunately, using typing.ForwardRef() can't be used as a suitable replacement, as jsons._common_impl.get_class_name() can't handle forward references:

>>> from typing import ForwardRef
>>> from jsons._common_impl import get_class_name
>>> get_class_name(ForwardRef("module.FooBar"))
"FooBar')"

I may have misunderstood what kind of registrations set_deserializer accepts; I've registered a Dict[str, "module.ObjectType"] deserializer before, where this deserializer was successfully matched against a dataclass with a matching Dict[str, ObjectType] field (note the forward reference in the registration and the lack of such a reference in the concrete object; Python passes in a Dict[str, ForwardRef('module.ObjectType')] object to set_deserializer in that case, but I suspect now that only typing.Dict is being registered in that case and so I got lucky.

I indeed misunderstood, and currently the use-cases I had in mind won't work with jsons (yet). This bug report is not a valid one with the currently supported feature-set so I'm closing this.
