That part is limited to `vindex` only. A single boolean index would always work in plain indexing and you can mix it all up inside of `oindex`. But with fancy indexing mixing boolean + integer seems currently pretty much useless (and thus the same is true for `vindex`, in `oindex` things make sense). Now you could invent some new logic for such a mixing case in `vindex`, but it seems easier to just ignore it for the moment. - Sebastian > Or is boolean indexing preserved as-is n the newest proposal?
