So, if you need to be able to do !obj in the general case, 
that's not going to
work
...
import std.stdio;

struct S {
  int x;
  bool opCast(T)() if (is(T == bool)) {
    return x == 0;
  }
}

void main() {   
  auto s = S(1);
  auto b = !s;
  writeln(b);   // true
}

Is this not supposed to work?
