import std.stdio;

void main() {
  int[] as = [111, 666];
  writeln(as);
  as ~= as[$ - 2]; //!<- doesn't append 111 but the one right to it
  writeln(as);

  //! subtracting one more works correctly
  int[] bs = [111, 666];
  writeln(bs);
  bs ~= bs[$ - 3];
  writeln(bs);

  //! fetches memory outside of array
  int[] cs = [111];
  auto mem = *(&cs[0] + 1);
  writeln(cs);
  cs ~= cs[$ - 1];
  writeln(cs);
  assert(cs[1] == mem);
}

!!! 64-bit specific error !!!
Assign appending using the dollar op fetches the wrong value.
Behaves as if the array length is updated before evaluating the dollar op.
