Small nitpick, even though it's not required, it might be clearer that this mutation and the assertion are related if they were in a do block or logically grouped in some other way like doto). Not a big thing just weird to see mutating code in Clojure without a ! suffix, but I won't block on this

I agree this mutable code is surprising but I don't see how to test this case differently. I wonder why aset is aset and not aset! 😅

clj-kondo warns of "redundant do" when adding a do under let.

I don't see how to apply doto here 🤔

Oh yeah since you're testing v rather than arr in the assertion that wouldn't work, I'll drop the comment, thanks for checking
