toy bank model based ideas from on David Nolan's The Power of Toys
;; tring out some ideas from David Nolan's talk [The Power of Toys](https://www.youtube.com/watch?v=fgRt0ecWfEE)
;; 1) a toy language, eg: `{:action :deposit :acc-id "acc-2" :amount 600}`
;; 2) a model where every function takes in the state of the world & returns an updated state of the world
;; (the talk is also about using simple property-based testing to generate programs written in the toy language, I haven't tried that)
;; src/bank-model/core.clj
(ns bank-model.core)
(defn increment-time [world]
(let [updated (+ 1 (get-in world [:time] 0))]
