All but the most inexperienced lispers read code by indentation. Also, pretty much any language that parses to an AST could easily output same as s-expressions if desired. Which incidentally is something I enjoy so much about Lisp. It makes it trivial to reason about code as a tree of structured objects instead of a string.
