non-const function override can cast away const

[Steven Schveighoffer]

Don't know if this has already been reported, but it definitely needs 
attention.

import std.stdio;

class A
{
  int x;
  const void f()
  {
    writefln("A");
  }
}

class B : A
{
  override void f()
  {
    x = 2;
    writefln("B");
  }
}

void main(){
  A y = new B;
  y.f;
}
