After reading the code, I thought the surprise was that it 
printed "true" :)

Perhaps making the default foreach behavior to make copies of 
structs wasn't the best idea, also due to performance reasons. 
One way it could have been designed was to force one of "auto", 
"const" or "ref" to indicate the "storage class".
