something about C/etc is bad for nesting heavily.

Edit: example. both lisp-style versions are nicer. if C has advantages, it isn't in making state work better.

  (def avg (numbers)
    (/ (sum numbers) (count numbers)))
  
  (def avg (numbers)
    (= total-number (sum numbers))
    (= total-count (count numbers))
    (= result (/ total-number total-count))
    result)
  
  function avg (numbers) {
    /(sum(numbers) count(numbers))
  }

  function avg(numbers) {
    =(total-number sum(numbers))
    =(total-count count(numbers))
    =(result /(total-number(total-count))
    result
  }
