I think Christine Webber should be nominated the `Honorary Scheme Archeologist'. Rather than reinventing the wheel (as the Rust community appears to be doing) she pulls out these gems and encourages others to look at them. And because I am looking at prescheme: my vote for dustycloud.org/blog/guile-stee. And then there is a lot more - look at goblins, hoot etc. It is quite incredible.
