  // The PHP parser sets internal compiler globals for certain things. Annoyingly, the last docblock comment it
  // saw gets stored in doc_comment. When it comes to compile the next thing to be include()d this stored
  // doc_comment becomes owned by the first thing the compiler sees in the file that it considers might have a
  // docblock. If the first thing in the file is a class without a doc block this would cause calls to
  // getDocBlock() on said class to return our long lost doc_comment.
  // To workaround, cause the parser to parse an empty docblock. Sure getDocBlock() will return this, but at least
  // it's harmless to us.
