"yield is reserved word" in ES6

Question

I'm getting this error in a react-redux-saga project:

Syntax error: yield is a reserved word (66:16)

 function* broken(action) { 
  props.forEach(prop => {                                                    
    const res = yield put(blah)   
    // do stuff yada yada in here                                                                           
  })
}

Turns out the internal function needs to be a generator too - but that then causes, erm, problems. So best to use a standard loop with no callbacks. Something like:

function* working(action) { 
  for (const prop of props) {
    const res = yield put(blah) 
    // do stuff yada yada in here                                                                           
  }
}
