> ...break the shared code paths into a palette of smaller subfunctions/subcomponents and then have each use case have its own high level code path that picks and chooses from these subfunctions: One does ABCDE, another does ACDEX. It makes it supremely easy to reason about what each of them actually do, because they read almost like a recipe. It becomes a sequence of high level steps, some of which are used by several use cases, while others are unique.
