var a = function(s) {
  return s + 'a';
};

var b = function(s) {
  return s + 'b';

var c = function(s) {

  // anything that blocks could go here
  var t = new Date().getTime();
  for (var i = 0; i < 1000; i = i + 1) {
    console.log(i);
  }
  var e = new Date().getTime() - t;
  console.log('blocked for ' + e + ' ms');

  return s + 'c';
};

var d = function(s) {
  return s + 'd';
};

var k = ['a', 'b', 'c', 'd'];

// runMe starts out as whatever needs to be passed to the innermost function

var runMe = '""';

for (var i = 0, n = k.length; i < n; i = i + 1 ) {
  runMe = k[i] + '(' + runMe + ')';
}

// every time you do this, Doug Crockford feels a sharp stab of pain

console.log(eval(runMe));
