Yeah, let’s face it: currently writing these interfaces is really confusing largely because of the typing. I’ve posted my ideas for an overhaul [here](https://discourse.julialang.org/t/proposed-overhaul-of-datastreams/3677). Certainly we also need much better documentation.

Currently traversal is always column-major (as in columns first, as far as I know), but one of my proposals is to change that.
