I've just written the following code, and I'm not proud of it. It's about as non-functional as you can get! Can anyone give any pointers to improvements ? I obviously want to get away from mutable lists, and vars for a starter. Please be gentle :wink:

// in this case the string is a sequence of words, no longer than 3 chars long, separated by spaces.
// the function splits the string into a list of strings, each no more than 67 chars long
private val String.chunky: List&lt;String&gt;
    get() {
        val list = mutableListOf&lt;String&gt;()
        var line = ""
        var data = this.split(" ")
        data.forEach {
            line = "$line$it "
            if (line.length &gt;= 67) {
                list.add(line.trim())
                line = ""
            }
        }
        list.add(line.trim())
        return list
    }
