That is exactly what I wanted to point out! I reduced the example code
to make that point more obvious:


import std.stdio;

class A {
  string x = "A";
}

class B : A {
  // should it be legal to hide a symbol and redefine it to a new type?
  int x = 2;
}

//static assert (is(typeof(A.x) == typeof(B.x)));
//Error: static assert (is(string == int)) is false

void main () {
  B o = new B();
  writeln((cast (A)o).x); // A
  writeln((cast (B)o).x); // 2
}
