It has been has been so long since it was first mentioned that it is hard for me to explain clearly why this is indeed not compilable but it is not. I guess if one can't explain something clearly one should shut up. It leads to situations which are logically unresolvable. As someone who has taught compiler construction it should be obvious ot me why this is true but my senior moments have caught up with me. If the detailed explanation comes to me I will share it. -- ======================================================================= All your files have been destroyed (sorry).
