Now as 1.9 is out, are there any plans for next version(s)? looking for https://dev.clojure.org/jira/browse/CLJ-1814 which has effect on library design.

I'm also looking forward to seeing what 1.10 will bring!

I’m doing (in-ns 'a.thing) and then (defn foo [] ...) to overwrite the behaviour of a var in a lib

the ns that does this is loaded properly but for some reason sometimes the overrides disappear

anything I’m missing or should I just stick to alter-var-root? I assumed def’ing over something would work

it is a pretty hacky solution regardless but I can’t figure out why sometimes the changes apply and sometimes they don’t

direct linking?

not enabled, no AOT either

ah found it … I am hacking cljs.core which is loaded via load dynamically “later” not via the usual require so it ignores that it was already loaded

is there a destructuring :or for namespaced keywords that works in clojure 1.8 and 1.9?

(let [{:keys [::foo] :or {foo 12}} {}] foo) works in 1.9 but not 1.8, and (let [{:keys [::foo] :or {::foo 12}} {}] foo) works in 1.8 but not 1.9

in short, no

I have this issue in tools.deps.alpha which I’ve tried to make work with both and I’m just not using :or for this case

yeah that seems like the implication for libraries
