Nice examples. Am I correct in guessing that this code: (ns com.stuartsierra.component (:require [com.stuartsierra.dependency :as dep] [com.stuartsierra.component.platform :as platform])) requires the correct platform.clj or platform.cljs depending on the runtime? And that this: #?(:clj (defmethod clojure.core/print-method SystemMap [system ^java.io.Writer writer] (.write writer "#<SystemMap>")) :cljs (extend-protocol IPrintWithWriter SystemMap (-pr-writer [this writer opts] (-write writer "#<SystemMap>")))) is how you perform different operations in a single file based on runtime?
