 Known Issues
 ============
 
- * Parsing expressions of type `a::$b[c]()` (I.e. the method name is specifed by an array)
-   currently does not work (causes 1 parse fail in test against Symfony Beta 3).
  * When pretty printing strings and InlineHTML those are indented like any other code, thus causing
    extra whitespace to be inserted (causes 23 compare fails in test against Symfony Beta 3).
