import api from './path/to/api'
import { take } from 'redux-saga'

function* watchSave() {
  while(true) {
    const { data } = yield take('SAVE_DATA');
  
    // Just naive example that callbacks do not propagate yield*
    yield* data
      .forEach(function*(record) {
        yield api.save(record)
      }); // this may be some non-trivial non-generator friendly function
  }
}

yield data.forEach(function*(record) {
        yield api.save(record)
      }); 

why not using map instead???

@slorber we've been discussing this with @yelouafi on twitter. You guys probably missed my pain point and it's the fact that you simply can't use HoF with generators. Of course, I am aware that it can be mapped over but this is a trivial use case - there'r many use cases when you simply have a lot of code implemented which heavily relies on callbacks - and this can't be used because callbacks do not propagate yield* automatically.
