Clojurians Log v2

I'm trying to learn Common Lisp and I'm stuck on something.

(map 'list '+ (mapcar
                (lambda (s)
                 (sums-of-children ht s))
                children))

For context, this is inside a recursive function, sums-of-children , which returns a list of (<int> <int>) if it's a leaf and the sum of it's children (`(<sum of children car> <sum of children cadr)`) if it's not a leaf.

Ah hah. A misunderstanding of apply. Simple. Just put apply at the beginning of that first form I'm using. https://stackoverflow.com/questions/2627262/how-do-i-splice-into-a-list-outside-of-a-macro-in-common-lisp
