I think that the programmer can always cheat. E. g. how about
(true?this:this).x? Or ((TypeName)this).x. So there's no point to
overcomplicate the compiler further to handle more cases as something will
still be unsupported. After all one can always declare instance method like
TypeName getThis() { return this;} and use getThis().x.

With best regards,
