hiding a class property behind a method

[luka8088]

It seems to me that the following code should be illegal, but I am
uncertain of it so I am posting here for a confirmation before I post it
on bug tracker:

import std.stdio;

class A {
  string x () { return "A"; };
}

class B : A {
  override string x () { return "B"; };
}

class C : A {
  string x = "C"; // should this be illegal?
}

void main () {
  A o1 = new B();
  writeln(o1.x); // B

  A o2 = new C();
  writeln(o2.x); // A
}
