If I understand correctly, the closure associated with f will be  
collectable after the lazy_t is forced, whereas before its lifetime  
would be bound to the lifetime of the lazy_t. That's very subtle. It  
would have taken me some time to track that one down if it had come up  
in practice. Thanks,
