On the other hand, I agree with Peter that it can be somewhat ugly. Maybe some alternatives, based on (values)?
(defun f () (for-effect (setq *foo* 'bar)))
Actually your example hints to a case where I *do* want a for-effect function to return a value, because setq does - which is also a strictly for-effect function. Similar, I like methods to return the object they were called on in a Smalltalk-style, if there is nothing better to return. Only when there is absolutely nothing useful to return, I would consider something like (values)
