weak: Documentation: clarification if `weak.Make()` moves objects from stack to heap

[pjebs]

func X() {
x := 9
p := weak.Make(&x)


}

https://cs.opensource.google/go/go/+/refs/tags/go1.24.4:src/weak/pointer.go;l=67:

// Make creates a weak pointer from a pointer to some value of type T.
func Make[T any](ptr *T) Pointer[T] {
// Explicitly force ptr to escape to the heap. <------ ???

Can the documentation clarify if weak.Make makes objects that should be in the stack move to heap?

In the above snippet, will x get moved to the heap? It is meant to only be used within X() and does not otherwise escape.

It does currently escape its argument.
That doesn't mean we want to promise that it does, or that it doesn't.

I don't think there's anything to change here. Escapiness is not an observable property of the language. (Except for library functions like testing.AllocsPerRun).
