Transducers build up transformation steps, with new generic operations like single arg `map` and `filter`, and then apply these transformations to a collection using an evaluation function. This function decides if operations are done lazily, eagerly, or on a channel.
Note that while this makes the place where laziness occurs more obvious, it is not really new. You can currently infer as well that `map` `filter` `concat` e.t.c are lazy. While `mapv` or `filterv` are not.
