I prefer loop/recur to TCO. You know exactly when you are, and are not, in tail position (which can be a bit obscure) and the compiler won't let you recur from non-tail.
- lispm 10y agoloop/recur handles only a tiny part of TCO. TCO means all calls in tail position are optimised, not just the self-recursive ones. Personally I find loop/recur ugly. It's a partial hack around the lack of TCO. Though I prefer looping statements like Common Lisp's ITERATE, whose design I like a lot... https://common-lisp.net/project/iterate/doc/index.html https://common-lisp.net/project/iterate/doc/index.html
