When I was playing with Scala there where a few cases where tail
recursion made a significant performance boost.

Is some time ago, so I do not remember which.

That is the difference between Scala and Clojure. Scala does it
silently, while by Clojure you have to say you want it. When a chance
breaks tail recursion Scala just compiles, but your code becomes
slower, Clojure does not compile. I prefer the Clojure variant.
