Shoot, now I can't remember. How many did we test? Well, this much is 
certain, there is at least one compiler that does dynamic initialization 
for it. :-/

I also seem to recall that there was still some question as to whether 
the use of the reference violated the ODR, if the reference is not 
optimized away. I don't think we ever got an answer to that question.
