As a follow-up to bug 1500811 (rvalue-qualified accessors), it would be nice if Maybe's apply and map functions had rvalue-qualified versions.

This way, the contents (if any) could be moved to the callback, e.g.:

  GetMaybeThing().apply([](Thing&& aThing) {
    /* Steal contents from aThing */
  });
