Thank you for the explanation! I didn't realize the difference.

OTOH, do you think that those arithmetic warnings are practical (as 
opposed to being correct)?
I understand the rules of the language(s) but honestly I expect the same 
behavior for short and for int in expressions like those. And in cases 
where I don't expect it I'll be careful about result type anyway.
