Console.log Shortcut

Here is console.log shortcut which could be useful debugging tool:

// usage: log('inside coolFunc',this,arguments);
// http://paulirish.com/2009/log-a-lightweight-wrapper-for-consolelog/
window.log = function(){
  log.history = log.history || [];   // store logs to an array for reference
  log.history.push(arguments);
  if(this.console){
    console.log( Array.prototype.slice.call(arguments) );
  }
};

It is taken from this Paul Irish blog.

Though here is various alternatives to console.log with added advantage which I have not checked.
