What we need is like a "Logo" for systems engineers / devops which is a simple toy language that can be described entirely in a book the size of the original K&R C book. It probably needs to be dynamically typed, have control structures that you can learn in a weekend, not have any threading or concurrency, not be object oriented or have inheritance and be functional/modular in design. And have a very easy to use FFI model so it can call out to / be called from other languages and frameworks. I think Scheme would work, as long as you ban all uses of call/cc and user-defined macros. It's simple and dynamically typed, and doesn't have built-in classes or hash maps. Only problem is that it seems like most programmers dislike Lisp syntax, or at least aren't used to it. There's also Awk, although it's oriented towards text, and doesn't have modules (the whole program has to be in one file). It probably wouldn't be that hard to make this language yourself. Read the book Crafting Interpreters, which guides you through making a toy language called Lox. It's close to the toy language you describe.
