 *   continuously called until the buffer is equal to the requested read size.
 *   Subsequent read calls will first read from the buffer and then call `next`
 *   on the underlying iterator until it is exhausted.
 * - `object` with `__toString()`: If the object has the `__toString()` method,
 *   the object will be cast to a string and then a stream will be returned that
 *   uses the string value.
 * - `NULL`: When `null` is passed, an empty stream object is returned.
 * - `callable` When a callable is passed, a read-only stream object will be
 *   created that invokes the given callable. The callable is invoked with the
 *   number of suggested bytes to read. The callable can return any number of
 *   bytes, but MUST return `false` when there is no more data to return. The
