<div>
<pre>struct Base { int a; };
struct Derived : Base { int a; };
int main() { }
The code snippet above produces no warnings with `-Wshadow` enabled.
This seems like an unusual situation that could lead to unexpected behavior.
I suggest producing a warning when `-Wshadow` is enabled, to alert that
`Derived::a` is shadowing `Base::a`.
