Passing this to void *

[Tim Hsu via Digitalmars-d-learn]

I am a C++ game developer and I want to give it a try.

It seems "this" in Dlang is a reference instead of pointer.

How can I pass it as void *?

void foo(void *);

class Pizza {
public:
    this() {
        Pizza newone = this;
        // works but newone is actually not this pizza.
        foo(&newone);
        // this does not work..
        foo(this);
    }
}

void main() {
    Pizza pizza = new Pizza();
    // this works...
    foo(&pizza);
}
