I see. I'm fine with having `void` here, what caught my attention was changing
`return ActOnObjCContainerStartDefinition(X);` into
`ActOnObjCContainerStartDefinition(X); return X;` that's perfectly fine though.

Comment at: clang/lib/Sema/SemaDecl.cpp:17067
+void Sema::ActOnObjCTemporaryExitContainerContext(ObjCContainerDecl *ObjCCtx) {
+ auto DC = cast<DeclContext>(ObjCCtx);
assert(DC == CurContext && "Mismatch of container contexts");

Interesting, I would expect that `ObjCCtx == CurContext` would have implicit
upcast of `ObjCCtx` to `DeclContext *`. Same for the assignment.
