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...');
}
