May be using [:a :b :c :d :e] as below instead of [1 2 3 4 5] makes it slightly easier to read the printed output?

# keys for tuple/array are 0-based index
# prints 0->a 1->b 2->c 3->d 4->e
(eachp [i x] [:a :b :c :d :e] (prin i "->" x " ")) # -> nil

For comparison, ATM, the original is:

# keys for tuple/array are 0-based index
# prints 0->1 1->2 2->3 3->4 4->5
(eachp [i x] [1 2 3 4 5] (prin i "->" x " "))
