8// the scope of what we ever intend to support in user code.
9// Returning an `Ref<T>` is supposed to be a core-module-only
10// thing, and even then is something that we would like to do less
11// of over time.
12//
13// The only purpose of this test *seems* to be ensuring that this
14// particular function (and the `groupshared` declaration inside
15// it) "works," but the function itself is not something that we
16// intend to be supported in Slang.
