I don't know if I'd call that shadowing. This is how it works
in Java, too. There's no such thing as a vtable for member
variables -- each class gets its own set and they don't
conflict. The only time it could be really be called shadowing
is when the base class member is protected, as then it's
accessible in the subclass scope.
Also, it's not the same thing as overriding. Overriding means
that when you call base.foo(), you get sub.foo()'s
implementation. But when you access base.var, you get base.var
and not sub.var.
I would find it extremely annoying if it worked the way you're
expecting it to.
C# results:
main.cs(8,14): warning CS0108: `B.x' hides inherited member
`A.x'. Use the new keyword if hiding was intended
main.cs(4,14): (Location of the symbol related to previous
warning)
Compilation succeeded - 1 warning(s)

with "new" keyword that is used to hide a method, property,
indexer, or event of the base class into the derived class.
class B : A {
public new int x = 2;
// I tell "I want hiding. Ensure "x exists in parent""
explicitly
// almost same meaning as "override"
}
OT:
and again how to easy to google info about error/warning just
with one word "CS0108"
