The following code gives me an error saying:
Error: template instance opCast!(bool) opCast!(bool) does not match template
declaration opCast(T)() if (is(T == int))

The error disappears if the opCast is not defined.

struct Foo {
  int t;
  bool get() {
    return (t == 0);
  }
  alias get this;
  T opCast(T) () if(is(T == int)) {
    return t;
  }
}

void main() {
  Foo f;
  if(f) {}
}
