I don't know if this is a recent addition to clj-kondo but toString is flagged in the followed as an "unresolved protocol method":
user=> (str (reify clojure.lang.IReduceInit (reduce [_ _ _]) (toString [_] "Hello!")))
"Hello!"seancorfield 2025-08-21T19:58:12.008609Z
The real-world version of this is in next.jdbc for the various plan implementations that do something similar to the above.

Object ?
seancorfield 2025-08-21T20:01:58.485599Z
Yeah, I was sort of thinking that but reify is for "a protocol or interface" -- and Object is neither -- but, you're right that it works and silences clj-kondo...

Ah, Object is called out as a special case for reify in the docstring!

a good reminder to go read the docstring again

(ah! not to you. i mean a good reminder to me!)

I guess I was a bit surprised that the original code worked, once clj-kondo flagged it. TIL 🙂

yes, Object :)
