I am attempting to turn it into an Enumeratee in the Play Framework, but I am having difficulty getting started. My algorithm has local mutable state and synchronous operations and looks something like this var state = 'foo var i = input() while (i != null) { if (state == 'foo && i >= 0) { // 2 outputs,
