Make sense to me.
I don't know offhand who might be a good second pair of eyes to take a look.
================
Comment at: clang/test/SemaObjC/objc-precise-lifetime-unused-variable.m:6-8
+ // no diagnostics for objects with precise lifetime semantics.
+ __attribute__((objc_precise_lifetime)) id x;
+ x = getFoo();
----------------
Is it worth adding some cases with nested scopes? I think that's a common scenario where `objc_precise_lifetime` is often used?
