No (it was discussed some many months ago). It may looks like a  
write‑in‑place statement, but that's only an appearance, nothing specifies  
it should have this behavior. For non‑limited types, the extended return  
statement is exactly the same as a classic return statement, wrapped in a  
local scope (as with a declare/begin/end block) with a locally declared  
variable. Nothing special with this construct when not applied to a  
limited type.
