And for sure, it's possible to do it in all sorts of languages: python, ruby, js, go, and of course lisp I get that the syntax is "weird", but honestly, the only two real difference is that the parens are "on the wrong side" for functions/expressions, and the indentation is truncated (the trailing side of the paren pyramid is accumulated and stuck to the end of the last functional line).
