I think that compilers should never generate warnings in these cases. If 
you overflow in arithmetic operations of same types, it is at most 
runtime error issue. You should know how large values can be stored in 
basic types, and use large enough data type in the code.

Since explicit casting easily hides bugs, it should not be used 
overwhelmingly.

That is very good example, why it would be good to have possibility to 
(temporarily) generate code even when it has warnings. That way the 
warning does not go anywhere and you still can debug your program.

Thanks! :)
