--- Comment #1 from Aaron Ballman <aa...@aaronballman.com> ---
Clang currently supports -Wshadow-field to catch exactly this situation. It's
not enabled by -Wshadow because this diagnostic has a fair number of "false"
positives that users aren't always interested in dealing with. Consider this
case:
struct S {
int x, y;
};
struct D : S {
int z;
int f() {
return z;
}
};
Everything is great -- there's no shadowing. Sometime later, a developer goes
and changes the definition of S to:
struct S {
int x, y, z;
};
This creates a shadow within D, but it didn't actually break anything either.
