Sure thing.
I also do this sort of thing for sphere sweeps and prisms - all the data gets
put into an array, and then I can make a spline for the sphere sweep, or use a
loop and grab the xz data for the prism.

I can always move "forward" from an array, since the data is always fully
accessible for anything I want to use it for.  I can't go "backward" if that
data is hard-coded into some other single-purpose container.
