    Effect.delay(1000),
    Effect.timeoutOption("500 millis"),
  );

    InternalServerError: { reason: string };
  }>;
  const { $is, $match, InternalServerError, NotFound } =
    Data.taggedEnum<HttpError>();
  
  // create a matcher
  const matcher = $match({
    NotFound: () => 0,
    InternalServerError: () => 1,
  });
  
  // true
  $is("NotFound")(NotFound());
  
  // false
  $is("NotFound")(InternalServerError({ reason: "fail" }));
