When passing to use parameter pack function itself as a parameter to a different function (as a completion handler etc.) it will crash the compiler in Xcode 15 beta 1. Attached a simple playground with two different examples, which both crash. Not sure if this if passing parameter packs as a closure is supported, but is definitely should not crash. I expected parameter packs to be able to replace the code generation for this library, which has some very nice basic use cases for paramer packs: https://github.com/mkj-is/NoopKit#usage-examples

This works both in Xcode 15 and Xcode 15.0.1.
Still present in Xcode 15 beta 2.
