@TehPers @cm0002 I guess I can somewhat empathize with the author. But you're right, the author seems to be frustrated that some things are inherently complex. Though, Rust has terrific documentation and a lot of literature to get enough understanding to where things aren't necessarily runes anymore, but rich in meaning.
I will say though, does nalgebra require custom derive macros? If you need to parse ast on the regular to use a library, I can definitely agree with his point on complexity.
