I see debate again about whether openSCAD can be a proper programming language without assignment The thing is that openSCAD is a functional language like many others. I also use XQuery to develop entire web applications and it too is functional. For the past month I've been working on code to implement the Conway polyhedra operators in openSCAD. There are implementations in JavaScript and Python but not AFAIK in openSCAD or in a functional language. The script is on Github https://github.com/KitWallace/openscad/blob/master/conway.scad and now implements all but one of the operators (cant get my head around whirl!) with some additions such as a shell operation. The script enables complex polyhedra to be constructed entirely in 'user-space' (is that the right term?) as points and faces until turned into a solid via polyhedron(). The code could do with some re-factoring but I think it is a good example of the power of openSCAD and functional languages in general. Development has been greatly eased by recent enhancements, particularly list comprehensions and let(), and by my realization that search() facilitates associative arrays. Aside from a few functions summing values in an array where reduce() would avoid the need for recursion, I never missed assignment. Programming in a functional language does however need a different mindset which takes time to acquire. OpenSCAD as a language has made huge advances since I started using it a couple of years ago and my thanks go out to the team for a great project. Of course, function parameters are top of my list for further work to make openSCAD more fully functional.
