WebI'm perfectly aware of the situations when one actually needs dynamic payload, thank you. The description in the post, however, sounds more like the type of payload should be statically known, but the exact type is not decided yet. In this case introducing anything dynamic is counterproductive. WebThe type of this thing is pretty horrific. I think you need dependent types to express the relation between the numeric argument and the length of resulting tupple. This is possible, but requires way more typing machinery than Rust or standard Haskell have. Despite the type being hard, using this function in Python is easy.
