 Sometimes you may forward a composite parameter piecewise, each subobject once on every static control flow path:
 
     template<class PairLike>
-    inline auto test(PairLike&&... pairlike)
+    inline auto test(PairLike&& pairlike)
     {
         // ...
         f1(some, args, and, forward<PairLike>(pairlike).first);           // forward .first

This PR removes a stray ellipsis where the author clearly didn't intend to use a parameter pack.

The code is ill-formed without this fix.
