Very impressive work! I was thinking of letting components not only implement the Lifecycle protocol but also a protocol that defines the functionality of the component. To give a simple example, there could be a jdbc component that establishes a connection on init etc., and which also implements a JDBCProtocol, e.g. functionalities such as provided by clojure.java.jdbc/query etc. Does that make sense?
I ask because I didn't see any of the extensions or examples done in this way, and because there doesn't seem to be much code that supports fetching and manipulating the system map which seems to speak against this approach?
