What's the one-level sequence flattening function in Clojure?
clojure, functional-programming
Solution
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.
Problem
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.
