Annotations in PHP

Yesterday someone proposed adding support for annotations to the PHP Interpreter. Although it would be nice to have this kind of functionality out-of-the-box and built into the interpreter itself this is not necessary. I could not resist and started working on a package that exends the Reflection API of PHP 5 by adding getAnnotations(), getAnnotation($name), and hasAnnotation($name) methods to ReflectionClass, ReflectionFunction, ReflectionMethod, and ReflectionProperty. The syntax for annotations follows the standard for PHP Doc Comments and @foo bar declares an annotation of name "foo" with value "bar". The inital code can be found here:

A usage example can be found here.
