I apologise for the poorly formatted response as I currently receive the list in digest (a mistake I have learned).
Your use case may be addressed by the __FUNCTION__ literal expression which could be defined as the property’s name when within a behaviour?
This has previously proven useful when defining associated objects, for example: (sel_getName(Selector(__FUNCTION__)))

As proposed, we have Self and self for referring to the type and instance of the container and newValue for referring to the new value in the core getter. A predefined local variable "name" of type String, bound to the name of the decorated property, would be handy for implementing things like Brent's backedByJSON behavior:
