3/// Marker for goal state.
4///
5/// This is used for referential param values, where an item param value is
6/// dependent on the state of a predecessor's state.
7///
8/// A `Goal<Item::State>` is set to `Some` whenever an item's goal state
9/// is discovered. enabling a subsequent successor's params to access that value
10/// when the successor's goal state function is run.
11///
12/// Note: A successor's goal state is dependent on the predecessor's goal
13/// state, which should be in sync with its current state after
14/// `ApplyFns::exec` has been executed.
