Hello,
Is it intended that calling `await` on an agent triggers the watch
functions?
user> (defn watch1 [& args] (apply println args))
#'user/watch1
user> (def a1 (agent nil))
#'user/a1
user> (add-watch a1 :w1 watch1)
#agent[{:status :ready, :val nil} 0x267236ca]
user> (send a1 (constantly 1))
#agent[{:status :ready, :val 1} 0x267236ca]
:w1 #agent[{:status :ready, :val 1} 0x267236ca] nil 1
user> (await a1)
:w1 #agent[{:status :ready, :val 1} 0x267236ca]
nil
user> 1 1
>From the implementation side I can see why this is the case, but cannot
find if this is documented as intended behavior:
https://github.com/clojure/clojure/blob/ee3553362de9bc3bfd18d4b0b3381e3483c2a34c/src/clj/clojure/core.clj#L3274
For one, it doesn't seem like waiting for an agent involves change in it
state in any way.
