Why do Agent.start_link/2, get/3 and update/3 take a function to set/get state? Why not just pass/retrieve the state directly, i.e., if I want the state to be 42, just let me pass 42 instead of fn -> 42 end?
This isn’t a complaint as I am sure there is a good (maybe obvious) reason for this, this question is really just a request for a learning opportunity for me if anyone is willing to explain.
