If my favorite part of redux is structuring flows with redux-saga, does mobx-state-tree have a solution for me?

For example, this is nice:

  // On login, spin off the auth process. If an error or a logout happens, clean up.
  // Be sure to cancel any pending auth request! 
  // Then get ready for a new login.

  function* loginFlow() {
    while (true) {
      const {user, password} = yield take('LOGIN_REQUEST')
      const task = yield fork(authorize, user, password)
      const action = yield take(['LOGOUT', 'LOGIN_ERROR'])
      if (action.type === 'LOGOUT')
        yield cancel(task)
      yield call(Api.clearItem, 'token')
    }
  }

(Genuine question...idk!)
