Summary: Pull Request resolved: https://github.com/facebook/duckling/pull/533 In recent versions of Data.Some the name of the constructor, `This` has changed name to `Some`. This has become rather problematic for us to migrate so we're just going to remove the dependency. The meat of this diff is adding the type `Seal` to `Duckling.Types`. That type replaces `Some`.
