 Performance
+	Each object type (class) needs fast access to:
+		Its identifying roles
+		Its supertypes that have alternate identification
+		The roles it plays in identifying other object types
+	Each one-to-many role needs:
+		A method to derive a counterpart (RoleValues) key from a full key
+	Each class needs
+		An adapt() method to convert offered values to a full key
+		an assign_all method
+			that can perform "atomic" identity change
+	Constellation needs assert_instance that for a given class:
+		adapts all keys from identifying values
+		checks either non-existence or uniqueness and type of the identified object for all such keys
+		instantiates the object if previously non-existent
+		(instantiates role subtypes by mixing in if this instance did not exist but the class is mixed in another extant object)
+		assigns non-identifying values
 	Pre-define ObjectType accessor methods on constellation, rather than using method_missing
