> Currently, the only method provided by the State interface is `clear()`. I think we should
provide another method called `get()` to return the structured value (e.g., value, list, or
map) under the current key. 
> In fact, the functionality of `get()` has already been implemented in all types of states:
e.g., `value()` in ValueState and `get()` in ListState. The modification to the interface
can better abstract these states.
