  /// Code completion itself is meant to be triggered by the client when the

  /// the expression \c p->get, the client should provide the location just after
  /// the ">" (e.g., pointing at the "g") to this code-completion hook. Then, the
  /// client can filter the results based on the current token text ("get"), only
