This function implements the message-handler attached to the class USER (see section 9.4.5.1). This function evaluates and places slot expressions given by the class definition that were not specified by slot-overrides in the call to make-instance or initialize-instance (see section 9.6.1). This function should never be called directly unless an init message-handler is being defined such that the one attached to USER will never be called. However, such a definition is unusual and recommended only to advanced users. A userdefined class which does not inherit indirectly or directly from the class USER will require an init messagehandler which calls this function in order for instances of the class to be created. If this function is called from an init message within the context of a make-instance or initialize-instance call and there are no errors in evaluating the class defaults, this function will return the address of the instance it is initializing. Otherwise, this function will return the symbol FALSE.
