Note that without the initial parameter, or without the destructor, they 
do NOT end up on the heap.

I think this is a bug, and not a "feature". I can't see any reason why 
in those two cases it can construct it on the stack, and in this case it 
cannot.

Note that I was under the impression that a Typesafe Variadic would 
always be on the stack. Reading the spec, it says it "may" put it on the 
stack, which makes me like those types of functions a lot less. Is there 
any reason a Typesafe Variadic function called with individual values 
cannot be required to put the values on the stack?
