"Closing the Stage" is about a different interaction between staging and closures: that (with some care) staging constructs can be elaborated into closures in an unstaged calculus. The problem with moving arbitrary values between phases with macros is that values can refer to bits of the runtime environment that cease to exist when compilation is finished. |

Exactly, which seems to provide the necessary semantics for references that you mentioned. Clarifying staging semantics for difficult abstractions like refs by elaboration into well understood closure semantics was the point of the paper.
