The best way in clojure is to return seq, or nil if its empty

Question

Is there a better way to implement this?

(if (empty? a-seq)
    nil
    a-seq)

Use the seq function , it does just that.

I don’t know how I missed this in the documents, but not-empty does exactly that (thanks Guillermo for re-reading the documents).
