 * Help me determine the best-supported flavor of variable annotations across PHP IDEs.
 *
 * 1. Open this file in your IDE
 *
 * 2. Place your cursor at the bottom of the file and see which variables are understood
 *    as instances of the class Foo
 *
 * 3. Report your findings to http://goo.gl/forms/qBO8OpLPlj
 *
 * Thanks!

// place cursor here, type var names, see if auto-complete for ->bar happens...
