You rarely write loops in K (KDB is 100% loop-free), instead you use adverbs. An adverb modifies a function, returning another function, changing the ways it operates over its arguments and what it does with it's return values." How about an interactive loop-like version? Generating the target set is good for baby test cases but not if the cardinality of the target is large. Does that make the problem more intersesting?
