    switch a
      when b
         , c
         , d
        e()

Not to mention that loop counters are no different than other `var`iables in JS.

    bar = ->
      alert "Holy crap cheese is awesome!"

    foo = ->
      for bar of bars
        console.log bar
      return

    var bar, foo;

    bar = function() {
      return alert("Holy crap cheese is awesome!");
    };

    foo = function() {
      var bar;
      for (bar in bars) {
        console.log(bar);
      }
    };

So we'd have to give up:

    array
    .map (x) ->
      f x
    .reduce (a, b) ->
      g a, b

(Or are you suggesting to allow such code? I personally see no value in it.)

    foo
      bar;
      bash: something;
      thenBlitz.
