Hi,
is there a way to use a dictionary returned from a task in the with Flow block? i read in some threads that it could be done using an intermediate task to unpack it,
any examples for such task?

So I always told people to unpack it, but I was wrong. You actually can.
```@task()
def abc(x):
    return {"a": 1, "b": 2}

with Flow("test") as flow:
    a = abc(1)
    test = a["a"]

flow.run()```

```@task()
def abc(x):
    return {"a": 1, "b": 2}

@task()
def bcd(x):
    return x

with Flow("test") as flow:
    a = abc(1)
    test = a["a"]
    bcd(a["b"])
    

flow.run()```

The `[]` for a task calls the built-in Prefect `GetItem` task

`@task`
`def a():`
  `return {'list_key':['item1',item2']}`

`with Flow('test') as flow:`
   `t = a()`
   `li = t['list_key']`
   `for item in li:`
      `do_something(item1`)

This I don't think so. You should use `.map()` instead to loop. And then you need to unpack this yep.
