> ARROW-9665 (https://github.com/apache/arrow/pull/7913) added amongst other
> things a {{head}} method for Dataset in R:
> https://github.com/apache/arrow/blob/586c060c8b1851f1077911fae6d02a10ed83e7fb/r/src/dataset.cpp#L266-L282
> It might be nice to move this to C++ and expose it on the python side as well
> (and since it's written already in C++ on the R side, it should be relatively
> straightforward to port I assume)
