I'm working on this new transformer thing that lets you build functions using data and I added a behavior that can spec check data while it's being constructed. What do y'all think about this transformer/spec api? It basically accumulates more and more spec constraints as transformers are derived from each other. Here you can see a transformer map that won't let a particular key be dissoc'ed from itself because of its spec: https://github.com/johnmn3/step-up/blob/main/src/step_up/alpha/transformer.cljs#L196 Any recommendations on how best to compose together specs from different map specs in an ad hoc manner? I'd like to keep it as an "open" system by default.
