Makes sense to me.   I image gcc backends don't natively support this 
because it's equivalent to casting to a pointer and dereferencing.

Do we really need it with ref return and force-inline?

pragma(always_inline)
ref ubyte PORTB() @property { return *cast(ubyte*)0x1000; }

That should also result in optimal asm, right?
