Make WordPress globals more accessible

Wordpress using a lot globals variables. These variables are used throughout WordPress code for various reasons. Great example is database connection object wpdb. Here is common example how to use wpdb in some function:

function something() {
  global $wpdb;
  /** @var wpdb $wpdb */
  $wpdb->query('SQL...');
}

It's highly uncomfortable and long! Therefore, I have prepared a simple object which make all global variables much more accesible from anywhere: https://gist.github.com/OzzyCzech/4737518 (PHP 5.3+ only)

function something() {
 Globals::wpdb()->query('SQL...');
}
