Ah, indeed, and that could have a great many of them alive at 
once. Blargh, it'd need a real allocator to handle freeing them 
out of order.

Nevertheless though, I still think the lifetime management there 
is simple enough for the user-programmer that freeing it manually 
isn't a big hassle and not worth making major changes to the 
language over.
