The VRP mechanics do not currently let that compile, so nothing 
will break. it would be equal to `E e = E.y`; `E e = cast(E)"y"` 
on the other hand would still be `E e = E.x`, as it's now.

Now, I admit that difference between implicit and explicit cast 
is confusing and a weakness.  Maybe the syntax should be `E e = 
".y"` instead to avoid the difference in behaviour between 
implicit and explicit cast.
