Awesome to see. Has always thought there were too few concat langs out there. And also really nice that you connect it really well it seems to func prog.
I've even felt this niche so underrepresented that I have been thinking about creating a language for it myself. So maybe you beat me to it, or rather I can look to you for some inspiration :p
Question: What made you chose to compile to Rust instead of to LLVM or something like that? Do you make use of the memory safety you gain this way in some interesting ways?
