That's sort of the point. It's "just Python". It's s-expression syntax for Python. Why would one want such a thing? Well, s-expressions confer many advantages (and of course, some disadvantages - it's good to have a choice!) - It makes it easy to write code that writes code, which is useful because it affords "compile-time" abstractions with no runtime performance penalty (in lisp terms, "macros"). - If you're comfortable with a structure editor, it enormously lowers the friction involved in refactoring. - It allows everything to be an expression: json.loads(with f as open("file.json"): f.read()) #doesn't work (json.loads (with [f (open "file.json")] (f.read))) ;works - It effectively removes all restrictions based around things fitting on a single line - lambdas are the canonical example.
