/**
   * A builder of a {@link ClosingFuture} step that is derived from more than one input step.
   *
   * <p>See {@link #whenAllComplete(Iterable)} and {@link #whenAllSucceed(Iterable)} for how to
   * instantiate this class.
   *
   * <p>Example:
   *
   * {@snippet :
   * final ClosingFuture<BufferedReader> file1ReaderFuture = ...;
   * final ClosingFuture<BufferedReader> file2ReaderFuture = ...;

### Refactors

* ♻ Remove `media_type` from `ORJSONResponse` as it's inherited from the parent class. PR [#5805](https://github.com/tiangolo/fastapi/pull/5805) by [@Kludex](https://github.com/Kludex).
* ♻ Instantiate `HTTPException` only when needed, optimization refactor. PR [#5356](https://github.com/tiangolo/fastapi/pull/5356) by [@pawamoy](https://github.com/pawamoy).
