One nice thing about Julia is that you basically never have to think about the indices. One of the primary reasons for this is that people using julia like array types with all types of strange and wonderful index sets (e.g. skew lattices to slice through a higher-dimensional array which people in medical imaging like apparently). As such, there are easy and convenient abstractions that are independent of the index space and all of the standard libraries and most external packages use these (to be able to deal with non-standard arrays).
