export default function interpretSequence(seq, rec, rej, res){

  //This is the primary queue of actions. All actions in here will be "cold",
  //meaning they haven't had the chance yet to run concurrent computations.
  var queue = new Denque();

  //These combined variables define our current state.
  // future  = the future we are currently forking
  // action  = the action to be informed when the future settles
  // cancel  = the cancel function of the current future
  // settled = a boolean indicating whether a new tick should start
  // async   = a boolean indicating whether we are awaiting a result asynchronously
  var future, action, cancel = noop, stack = nil, settled, async = true, it;

  //Pushes a new action onto the stack. The stack is used to keep "hot"
  //actions. The last one added is the first one to process, because actions
  //are pushed right-to-left (see warmupActions).
