No, it is used for loops within functions as well. But it’s not fully generalized like in Scheme. You can’t have mutually recursive functions using tail recursion via “recur,” for instance. There is another Clojure technique for that (“trampoline”). Clojure runs on the JVM and is limited by the JVM’s original omission of TCO. When I started using Clojure, I was concerned about these limitations, but in practice I haven’t found them to be a problem. Most of the time, I just need a loop and “recur” works fine. I rarely use “trampoline” (just for state machines).
