+;;;; testing raw slots harder
+;;;;
+;;;; The offsets of raw slots need to be rescaled during the punning
+;;;; process which is used to access them. That seems like a good
+;;;; place for errors to lurk, so we'll try hunting for them by
+;;;; verifying that all the raw slot data gets written successfully
+;;;; into the object, can be copied with the object, and can then be
+;;;; read back out (with none of it ending up bogusly outside the
+;;;; object, so that it couldn't be copied, or bogusly overwriting
+;;;; some other raw slot).
