That won't work on a multi-dimensional array. Ideally it needs to accept a slice or an element and return the specifier
forthe slice.
This wouldn't be so bad if we had an easier way to extract subsets of an array, but even that is really ugly because
whateveryou extract keeps the original number of dimensions.

This would actually be written in C though, yes? Otherwise it's not really any better than just doing an extension...
