No - in JSC I'm pretty sure it's going to be faster and cleaner to implement this as a regular accessor property.

Now, it would certainly be possible to add a mechanism to allow this accessor to masquerade itself as a data property, but it just seems too magical and unnecessarily weird to do so.  It behaves like an accessor, so it should look like one.
