Add case path for optional chaining #141

Closed stephencelis closed 8 months ago

stephencelis commented 8 months ago

While #139/#140 added support for flattening optionals, this PR adds support for chaining into optionals. This is useful for when an API takes a case key path to an optional value, but you want to chain into another value and keep things optional.
