  }
};


ns.bar.after = function (next, arg) {
  return next ? next(arg + 1) : arg + 1;
};

// Register hook after definitions
ns.bar = hook(ns.bar);

// Register hook before definitions
hook('ns.foo', ns);

ns.foo.after = function (next, arg) {
  return next ? next(arg + 1) : arg + 1;
};

ns.foo.before = function (next, arg) {
  return next(arg + 1);
};

ns.foo.before.after = function (next, arg) {
  return next(arg + 1);
};

ns.foo.before.before = function (next, arg) {
  return next(arg + 1);
