functional programming - What's the one-level sequence flattening function in Clojure?

Question

What's the one-level sequence flattening function in Clojure? I am using apply concat for now, but I wonder if there is a built-in function for that, either in standard library or clojure-contrib.

Answer 1

My general first choice is apply concat. Also, don't overlook (for [subcoll coll, item subcoll] item) -- depending on the broader context, this may result in clearer code.
