Alright, I see. In that case we should not create an entirely new syntax for this - unless there are more people than just me interested in this feature. I can just use my own little convenience function that generates a series of array indices that can be fed to isel, something like this:

python def wrap_iselkw(ds, dim, istart, istop): """Returns a kw dict for indices from `istart` to `istop` that wrap around dimension `dim`""" n = len(ds[dim]) if istart > istop: istart -= n return { dim : np.mod(np.arange(istart, istop), n) }
