2202 – Error getting type of non-static member of a class

The following fails with 'Error: this for x needs to be type C not type int':
class C
{
 int x;
}
typeof(C.x) z;

Not sure if that's really a bug or not. I lean towards "no" since typeof is supposed to take a variable, and C.x is not a variable. 
You can get what you want with typeof(C.init.x).

I'm not sure either as it worked before but is not mentioned in the specs. I wouldn't post it as bug if the following compiled:
static assert (!is(typeof(C.x))); // Fails with the same error, should pass
static assert (!__traits(compiles, C.x)); // Should pass
... and if this didn't compile:
struct S
{
 int x;
}
typeof(S.x) y; // Why this compiles then?
So it is either a regression or we have other bugs and inconsistencies.

in the essence, it's duplicated with bug 515
*** This bug has been marked as a duplicate of 515 ***

No, 515 is about whether .offsetof is static or not. This is about whether typeof(Class.nonstatic) should be allowed.

It's supposed to take an expression. C.x is an expression.

C.x is not a valid expression?

This example shows it's definitely a bug (1.047):
class C {
 int x;
}
alias C.x F;
static assert(is(typeof(F) == int)); // OK
static assert(is(typeof(C.x) == int));
//Error: static assert (is(int == int)) is false

PATCH: mtype.c, in TypeClass::dotExp(), around line 6350 in D2.032. Don't convert class.x into this.x if inside a typeof() and we don't have a 'this'.

	/* It's:

	{
	 e = new TupleExp(e->loc, d->isTupleDeclaration());
	 e = e->semantic(sc);
	 return e;
	}

	{
	 if (sc->func)
	 {
		ClassDeclaration *thiscd;
		thiscd = sc->func->toParent()->isClassDeclaration();
