Codegen test for
```
static union { int _ = 42; };
int &ref = _;
int foo() { return 13; }
static union { int _ = foo(); };
int main(void) { return ref; }
```
might be interesting.
I suspect that this case was missed in the committee discussion of the paper
@cor3ntin.

Less controversial tests to consider:
```
struct A {
int _;
union { int _; };
};
struct B { union { int _, _; }; };
```
