[OpenSCAD] Programming in Functional OpenSCAD

Thanks for looking at it.  Reading other people's code isn't always the
easiest thing in the world.  I'm still finding my feet in this purely
functional approach, so it's not surprising that it's ugly.  (TBH, I'm a
little surprised at how easily I got it working.)

A specific question is whether my sense that adding or removing any data
from a structure is always going to involve reconstructing the insert or
remove path, and it seems like the answer to that is yes.

Do you know if OpenSCAD has garbage collection or some other memory
management scheme?
