My intention is to programmatically generate a flow from these operations. The docs require that ids be keywords, but I would find it more natural to be able to use a unique id derived from the ops or a uuid. I can use something like `(-> (gensym "crop-") name keyword)` for generated proc ids, but that makes it feel like I might be doing something wrong.
