-By design, there is no access to variables in the parent class, file or global scope, no ''self'' or ''static'' or ''$this''.+By design, annotations expressions are evaluated individually in an empty scope - which means there is no access to variables in the parent class, file, local or global scope, e.g. no ''$this'', ''self'' or ''static''.
