Question: Tuple returns as arguments

How would you do something like the following, ie unpack tuple as arguments for next function within flow

```
@safe
def method_b(arg_a: str, arg_b: int) -> int:
return len(arg_a) + arg_b

@safe
def method_a() -> Tuple[str, int]:
return ("abc", 3)

a = flow(
method_a(),
bind(method_b)
)

a.unwrap()
>> 6

```
