I’m working with DifferentialEquations.jl and I have a state vector in 6-dimensional phase space. I would like to work with units and static vectors but my issue is that the momentum part of the phase space vector has a different unit than the position part. How can I get the functionality of StaticVectors.jl and Unitful.jl when I need two different units in my vector?

I found `ArrayPartition` from [RecursiveArrayTools.jl](https://github.com/SciML/RecursiveArrayTools.jl), which might solve my problem.

Edit: Jup, this does it.
