I've recently found dynamic pattern matching pretty valuable to completely replace REST-like server-side APIs with a data-oriented API that gets pattern matched and dispatched based on the actual values and shapes of the data structure. It helps almost completely avoid the /get/this /get/that /set/those explosion of API getters and setters that ultimately leads to very complex client logic that makes any notion of consistency at a distance very hard to reason about.
