In addition to vector-unzip, SRFI-43 defines several "common unzippers", but fails to specify how their names relate to vector-unzip's argument n. As far as I can tell from the reference implementation, the following holds: (vector-unzipn vec) == (vector-unzip vec (- n 1)). If this is true, however, then the reference implementation incorrectly defines vector-unzip5 as (vector-unzip vec 5). Regards Michael Burschik
