Thanks for the pointers. Trampolining is an old idea for obtaining tail-calls. It's a kind of folk-wisdom that has been rediscovered many times, as the related work here shows:

https://dl.acm.org/doi/pdf/10.1145/317636.317779

Usually the trampoline is implemented automatically by the language rather than forcing the author to confront it, though I can see why Clojure might have chosen to put the burden on the user.

Ah, I didn't know there was a HOPL paper! Some day I will have time to run a course reading HOPL papers. Some day I will have the time to read HOPL papers myself (-:. Thanks for the pointer.
