Simplify expression call inside falling through case

[hzlmn]

It is a feature request.
Currently this code sample

function bar(foo) {
  switch (foo) {
    case 'foo':
       log(a);
       log(b);
       log(c);
    case 'bar':
       return 2;
    default:
       return 0;
  }
}

converted to

function bar(foo) {
  switch (foo) {
    case 'foo':
       log(a), log(b), log(c);
     case 'bar':
       return 2;
     default:
       return 0;
  }
}

that could rather be converted to

function bar(foo) {
   return foo === 'foo' || foo === 'bar' ? (log(a), log(b), log(c), 2)  :  0;
}
