> The experimental {{map_batches()}} function is broken. The [one test for it|https://github.com/apache/arrow/blob/f8f2617d46e49616ab325e46542cf746293d0ebc/r/tests/testthat/test-dataset.R#L623-L636] has not been failing only because it calls the {{min()}} function which had no binding and thus triggered {{abandon_ship()}} to throw a warning and pull the data into R, preempting the error that would have happened later.
