Ok, I guess I was following the lapack naming convention. I was thinking,
e.g., workspace2 = { array1, array2 } with array being of any array type.
Vector would be another logical name. Alternatives could be
get_workspace_of<>, or get_workspace_array_of<>? Or do you have other
suggestions?

I meant temporary workspace arrays, instantiated for the minimal and optimal
cases. I though it would be clean to wrap these ones in a workspace-struct
and pass them on as if they were defined by a user.
