So what is the big advantage of this over OpenSCAD?

I found this:

https://docs.microcad.xyz/language/book/intro/preface.html

>While OpenSCAD is easy to learn and has a syntax reminiscent of C, we felt the language could be improved in several ways:

> - more specialization for creating graphics,

> - better support for modular programming,

> - strict typing and unit handling,

> - a syntax closer to Rust than to C,

> - a solid library system,

> - plugin support for other programming languages,

> - and a more powerful visualization concept.
