So we have a language called Clojure which groups by (... ([x] x) ([x x] x) ...); where there are complex evaluation rules... and [x1 x2 x3], where all x are evaluated and [v1 e1 v2 e2 ...], where only e is evaluated, in LET and [v1 ... vn], where no v is evaluated, in argument lists etc., etc. I somehow fail to see the dramatic improvement over just using parentheses. Instead of learning building basic rules of forming and naming expressions with parentheses, I now learn a few inconsistent rules of forming and expressions with a set of delimiters - which is no problem, but it is not the huge progress you claim.
