Looks great and I'm also curious about nested initializers.
================
Comment at: clang/lib/StaticAnalyzer/Checkers/DeadStoresChecker.cpp:420-421
+ // We should also allow defensive initialization of structs.
+ if (const auto *ILE =
+ dyn_cast<InitListExpr>(E->IgnoreParenCasts())) {
+ // We can use exactly the same logic here.

We probably won't because it's a C++ object, even though it's an aggregate so
we should probably warn(?) What about a plain C object like
```lang=c++
int x[2][2] = { { 0, 0 }, { 0, 0 } };
```
