Error compiling @rescript/core with Rescript 11

Your example can be fixed by explicitly uncurrying:

Console.log("Hello, world!")

-Console.log(List.make(~length=1001, 1)->List.reduceReverse(0, (acc, item) => acc + item))
+Console.log(List.make(~length=1001, 1)->List.reduceReverse(0, (. acc, item) => acc + item))
