yarn run v0.19.1
$ flow; test $? -eq 0 -o $? -eq 2 
The flow server's version didn't match the client's, so it exited.
Going to launch a new one.

src/hello/saga.js:13
 13:     fork(function* () {
         ^ function call. Could not decide which case to select
 13:     fork(function* () {
         ^^^^ intersection type
  Case 2 may work:
  396:     & (<R, Fn: Fn0<R>>(fn: Fn, ...rest: Array<void>) => ForkEffect0<null, Fn>)
              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ polymorphic type: function type. See lib: flow-typed/npm/redux-saga_v0.13.x.js:396
  But if it doesn't, case 3 looks promising too:
  397:     & (<T1, R, Fn: Fn1<T1, R>>(fn: Fn, t1: T1, ...rest: Array<void>) => ForkEffect1<null, Fn, T1>)
              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ polymorphic type: function type. See lib: flow-typed/npm/redux-saga_v0.13.x.js:397
  Please provide additional annotation(s) to determine whether case 2 works (or consider merging it with case 3):
   13:     fork(function* () {
                            ^ return
