JavaScript namespaces

Based on the Prototype namespacing made easy, except this doesn't require Prototype.

 String.prototype.namespace = function(separator) {
  var ns = this.split(separator || '.'), p = window, i;
  for (i = 0; i < ns.length; i++) {
    p = p[ns[i]] = p[ns[i]] || {};
  }
};

This isn't so much to ditch Prototype, but to encourage using namespacing.

You should follow me on Twitter here I'll tweet about JavaScript, HTML 5 and other such gems (amongst usual tweet-splurges)

Nicely done.

The "i=0" in the for loop should be declared as "var i=0", otherwise "i" becomes set at the global level - exactly what namespaces should be preventing.

@Mark - how on earth did I miss that! Corrected now - cheers.
