I've managed to create weird race conditions by adding watches while actions
are running. Are there guarantees about the scheduling of actions and
adding/ removing watches? If I add or remove a watch on an agent while an
action is running, what happens?
So to summarize, my feedback that still may b
Excellent point. Yes, get-watches seems like a better option.

I forgot to mention the reason I don't feel it should be an error to
remove a non-existent watch
user=> (dissoc {:a 1 :b 2} :c)
{:a 1, :b 2}

Just curious why you would want it to? Might you be equally served
with something like
(get-watches a) so you can determine if a key is there to be removed?
(defn get-watches [#^clojure.lang.

Hi Rich,
I like the flexibility of the new watches, but I'm missing a way to
watch for errors. Currently, if an agent's action results in an error
its watchers aren't even triggered.

Cool. I won't have much time to play with this until next week, but I
look forward to experimenting with it.

Is there a deep reason for this? I'm not familiar with this part of
Clojure but, if the functionality is possible, would you accept a
patch for this?

Never mind, I get it now.

Are namespaces & global set of namespaces "watchable" things ?

I've added (back) synchronous watches (svn 1309+), which used to exist
for agents, now for all reference types.
(defn add-watch
"Experimental.
Adds a watch function to an agent/atom/var/ref reference. The watch
fn must be a fn of 4 args: a key, the reference, its old-state,
