 ## Introduction  
-Swift’s variadic generics story (SE‑0393 “Parameter Packs” and SE‑0404 “Pack Iteration”) unlocks powerful abstractions over arbitrary arities. However, two missing features—recursive decomposition of packs in patterns and split‑expansion of packs at call sites—force library authors into brittle workarounds like fixed‑arity overloads or type erasure. This proposal completes the variadic‑generic toolbox by introducing:

However, two missing features—recursive decomposition of packs in patterns and split‑expansion of packs at call sites—force library authors into brittle workarounds like fixed‑arity overloads or type erasure. This proposal completes the variadic‑generic toolbox by introducing:
 
 1. **Pack Destructuring in Patterns** – extract `head` and `tail` from a variadic tuple in a `let` or `switch` pattern.  
 2. **Pack Splitting in Calls** – feed a single parameter‐pack expansion into separate head + tail parameters at call sites.

 ## Conclusion  
 By adding pack destructuring in patterns and pack splitting in calls, this proposal fills the last gaps in Swift’s variadic‑generic capabilities. Library authors can now write truly recursive, zero‑overhead abstractions without fixed arity limits or type erasure, while preserving source and ABI compatibility.
