Simple function chaining with a timeout (not ES5 compatible)

chain.js

Array.prototype.chain = function chain(delay) {
  var tasks = this, pos = 0, delay = delay || 17;
  setTimeout(function() {
    tasks[pos++]();
    if (pos < tasks.length) setTimeout(arguments.callee, delay);
  }, delay);
  return this;
};

// Usage;
var tasks = [];
tasks.push(func);
tasks.chain();
