Question

Does clojure have a powerful ‘loop’ like common lisp.

for example:

get two elements from a sequence each time

Common Lisp:

(loop for (a b) on '(1 2 3 4) by #'cddr collect (cons a b))

how to do this in Clojure?

Answer 1

By leveraging for and some destructuring you can achieve your specific example:

(for [[a b] (partition 2 [1 2 3 4])](use-a-and-b a b))
