The total number of parens in your examples is about the same, except you also have a bunch of noise like random semicolons sprinkled in. Meanwhile, nesting is a feature, not a bug because it provides you with additional visual information about relationships in code. The only people who incessantly bray about nested parens are the ones who've never actually worked with Lisp for any period of time. If this was a genuine problem with the syntax then stuff like sweet expressions would've taken off. The reality is, as I already explained and you've ignored, is that the editor manages the parens for you. When you work with Lisp, typing opening paren is equivalent to having a command sequence to say I'm starting a new expression.
