With the limited sample set of previous writing about this tooling - my impression is that it seems impossible to offer a succinct but still compelling description of this particular dialect of Rust. There are thousands of words of prose to describe it between this and the shell-scripting post, and a lot of code-level seams and abstractions introduced in the snippets. Yet I still can't tell you why I should want to do the new things that this code style would make possible for me to do. I also probably wouldn't enjoy trying to onboard a new contributor to a hypothetical project using this style, no matter how experienced with Rust they might be. DSLs, which I would consider CGP to be one, have a pretty high friction rate if they haven't become dominant/widespread.
