Hi Juan, Components are records in order to support the dependency-injection features of `component/start-system`, which work via `assoc`.
There are potentially many other ways to do dependency injection, but I found `assoc` to be practical. If you want to create a component that has a Lifecycle but no dependencies, then `reify` will work just fine. If you want to create a component that has dependencies but no Lifecycle, then an ordinary Clojure map will work. –S On Wednesday, April 29, 2015 at 2:41:54 PM UTC+1, Juan A.
