is possible?

now:
-------------
class Cfoo {
	void* adrThis;
	void saveThis(void* adr) {	adrThis = adr; }
}
...
Cfoo foo = new Cfoo(); foo.saveThis(&foo);

shall be
--------------
class Cfoo {
	void* adrThis;
	this() {
		adrThis = ?????????
	}
}
...
Cfoo foo = new Cfoo();

"this" should work

(pun intended)

However note that this is not the same as that function. 
cast(void*)this and &this are 2 different things. So if you want 
to do the same as saveThis just do void* thisAddr = cast(void*) 
&this; instead

void* thisAddr = cast(void*) &this;

Error compile: Deprecation: this is not an lvalue

This doesn't really make sense anyway, this is a local variable, 
you want to do cast(void*) this in a class if you need the 
address (which btw, you shouldn't actually, the reference itself 
ought to be enough)
