coffee script switch without break

Is it possible to use switch in coffeescript without break?

switch code                      switch (code) {
    when 37 then                     case 37: break;
    when 38 then           ->        case 38: break;
    when 39 then                     case 39: break;
    when 40                          case 40:
        ...                              ...

I thought this will work but failed:

switch code
    when 37 then continue
    when 38 then continue  ->    not valid
    when 39 then continue
    when 40
        ...
