Yes, and I asked if it's still ok for these two parts to go together. I can split it if there is a strong preference for that.
I haven't thought about the vector versions and I haven't seen any code that does this for vectors, so I'm not sure what patterns to look for. I don't know if the pattern for scalars would also apply to vectors.
I can add cttz.
