C'mon man, just introduce the "var" keyword and make everyone happy! <g>

eeeh .. ?
no no, that's awful!!
why would a RAII declaration have no "new"? Is it because it's going to 
be on the stack?
Why don't you instead introduce a special case for "new" to make it 
allocate on the stack, i.e.

var c = new(stack) Class(); //or newStack Class(); //or something else

which is a clean straight-forward version of:
