> Tamays should support type narrowing. Currently a user of Tamaya can only specify the concrete target type when getting a property value as object value.
> I would like to see support for type narrowing in Tamaya to according to these rules:
> Given an interface or abstract class A and a class B implementing or inheriting from A. If a user requests a property of type A Tamaya should be able to determine that B is a valid return value for this request and return an instance of B.
> Given an interface  or abstract class A and two classes B and C implementing or inheriting from A. If a user requests a property of type A Tamays should be able to determine that B and C are valid return values for this request and return an instance of B or C.
