For loop

for.cpp

// same code as in quill part, but in C++
{
  int i = 0
  contfunc = [&] () { i++; }
  while (i < 10) {
    std::cout << i << std::endl;
    contfunc();
  }
  std::cout << "Done counting" << std::endl;
}

for.quill

; for is a macro which must be imported
; Code below expands into something like code in cpp part, but in quill
(for (setv i:Int32 0)
 while (< i 10)
 step (set i (+ i 1))
 do
  (println (.toString i))
 after
  (println "Done counting"))

(do
  (defvar i:Int32)
  (set i 0)
  (defvar quill_continue_func:![]:Void)
  (set quill_continue_func
    (fn ![]:Void
      (set i (+ i 1))))
  (while (< i 10)
    (println (.toString i)))
  (println "Done counting"))

quill_continue_func will be called after each iteration
