That would have been nice too,  but too crippling as is. If and 
when we have all those sweet non-escapable references and 
whatnot, then maybe we could set it as optout by default via 
compiler switch?

Having "blocks tag-able with attributes" would help too. I wish 
more people would push for that. It would be an awesome feature, 
which I dare say would be as useful as the scope block.
