Just some basic questions concerning the code above. The documentation of nrepl/client says "Most REPL interactions are best performed via message and client-session on top of a client fn returned from this fn." So I am just wondering what the usual workflow is when reading stuff from the client and why I shouldn't use the f directly as above. message and client-session both seem to take a message as argument. What is the usual way to read repsonses asynchronously?
