* [x] For vectors, use them disregarding the value of `along`. This useful if we have e.g. the same ID type in a vector and columns in a matrix. * [ ] Allow `along=-1` etc. for the n-th last dimension not only in `split()` but throughout the package. * [x] Remove requirement that `along` has to be `1` if a `data.frame` field is referenced; instead, be consistent with above rule for vectors * [ ] Allow named vector for object references
