+  # A slot is a slot in an object. It is the storage location for a value.
+  #             (Remember, values are typed)
+  # From a memory perspective a slot is an index into an array (the object)
+  # The mapping into arrays is a straightforward matter, but happens in the
+  # next level down, the register machine.
+
+  # Four known objects exist and those correspond to subclasses:
+  # - the message that has been received: MessageSlot
+  # - the frame of the method that is executing (local variables): FrameSlot
+  # - self as an object: SelfsSlot
+  # - a message that will be sent, NewMessageSlot
+
+  # additionally frame, self and return are slots in Message and NewMessage
+
+  # Slot has a lot of small subclasses
+  # Names for the slots avoid indexes
