SELF-SOLVED Ha! My question had its own answer in it 🙂 It may not be stylish, but (tgen/fmap #(apply list %) (tgen/tuple …)) works. Hello test.checkers: I have a successful tgen/tuple generator, but it produces vectors and i want to produce lists. The following does not work: (tgen/fmap list (tgen/tuple …)) . I’m not surprised because the appropriate postprocessing would be something like (apply list (tgen/generate (tgen/tuple …))), but I don’t want to exit the generators via something like tgen/generate and then produce a list, I want a generator that produces a tuple-like list. I’d be grateful for advice!
