Hi Graham,
You might also be interested in https://hackage.haskell.org/package/implicit.
I don't know if it's more powerful, last time I tried it I had issues with 2D models though.
Kind regards,
Brecht

Hello Brecht,
This is interesting, in that it's the first I've heard of there being an OpenSCAD package for Haskell 😯.
I've been doing a fair bit of OpenSCAD design recently, and have frequently felt it would be nice express these constructs in Haskell or similar more fully featured functional source language. A previous search uncovered Haskell CSG packages, but I didn't see anything suitable for generating 3D printing files. (A search just now discovered https://hackage.haskell.org/package/mecha, which also offers OpenSCAD output.)
I understand that one of the problems with OpenSCAD as a target language is that it only exports to STL files, with no primitive recognition of curved entities. I believe there are other 3D model representations (OBJ, 3MF?) that have primitives for curved elements, which in turn can be handled more smoothly by GCode generation software.
(For non-3D printing folks reading this: GCode being the low level "machine" code that drives most personal 3D printers).
Anyway, I've tagged your fork of OpenCSG and will aim to try it out sometime 😀. Thanks!

Hi all,
I would like to take over the OpenSCAD[1] package, of which I believe the maintainer is no longer active. The maintainer hasn't replied to my ticket[2] on the issue tracker or to an email to the listed email-address for over a year. On my fork[3] I have implemented multiple bugfixes and features already, and I have some ideas for future improvements.
Best regards,
Brecht
