/**
 *  @deprecated 48.1.0
 *  This operator throws the `Error` contained in _input_ directly
 *  but its stack trace informartion lacks the information about where throws it actually.
 *  To keep it, use `unwrapOrThrowForResult` exported from following instead:
 *
 *  - `option-t/plain_result`
 *  - `option-t/plain_result/unwrap_or_throw`
 *  - `option-t/plain_result/namespace` exports it as `Result.unwrapOrThrow()`
 *
 *  It throw a new `Error` with keeping the original error as `Error.cause` property.
 *
 *  -------
 *
 *  Unwraps _input_, returns the content of an `Ok(T)`.
 *  Otherwise, this function throw the contained `unknown` __directly__ in `Err(unknown)`.
 *
 *  __We DO NOT RECCOMEND TO USE THIS function generally__.
 *
 *  This function is provided only to improve an interoperability with the world using "throw error" convention.
 *  __We do not recommend to use this function__.
 *
 *  @throws {unknown}
 *      This throws an inner value wrapped by Err(unknown)` __directly__.
