x is an reference to an instance of X, with other words a
pointer without arithmetic but with syntax sugar. &x will take
the address of this pointer/reference. If you want the address
of the actual instance, you can use cast(void*) for example.
Hi Tobias, can casting the address to void* make a difference
to its value?
No, try this:
import std.stdio;
class X {}
void foo(X x) { writeln(cast(void*) x); }
void main() {
X x; // null reference by default.
writeln(cast(void*) x);
foo(x);
x = new X;
writeln(cast(void*) x);
foo(x);
}
