Allow writability when chaining into a dynamic case #150

Closed stephencelis closed 6 months ago

While we should prohibit directly assigning a value through a case:

state.loggedIn = User(name: "Blob")  // 🛑

We can allow optional-chaining into a case's sub-value via an overload and some disfavoring:

state.loggedIn?.name = "Blob"  // ✅
