In the middle section of this https://day8.github.io/re-frame/images/subscriptions.png?raw=true, the code example for layer 3 is 

(reg-sub
  :greeting
  (fn [_ _]
    (subscribe [:get-name]))
  (fn [name]
    (str "Hello " name)))
It’s not clear to me why there are two functions here.

ah, the docstring for reg-sub has the answer.

And with the recent RC, you can write it as (reg-sub :greeting :<- [:get-name] :-> #(str "Hello " %)). :)
