Do you mean the ;: dyad? I am not completely sure what you mean by "look back" because all I can find on the subject are papers that require me to pay money to read them, and I am not inclined to do so. As near as I can tell, "look-back" in the context of state machines, has to do with restructuring the state machine so that you can take advantage of parallel hardware. J currently uses only one CPU, so if my understanding of look-back was correct, it seems to me that the concept is irrelevant to J's implementation. If your question was algorithmic in nature, can you pose a representative problem?
