Is there a possibility to create a recursive structure with a tagged pointer? As this does not compile, even without tagging bits.

´´´
import std.experimental.all;

void main(){}

struct A
{
    size_t dummy;
    mixin(taggedPointer!(
        A*, "x"
        /*,
        bool, "b1", 1,
        bool, "b2", 1
        */
    ));
}
´´´
with an error message
source/app.d-mixin-8(8,15): Error: variable `app.A._x_ptr` cannot be further field because it will change the determined A size
