I don't think it makes sense to allow adding two characters - the 
second operand should be an integer type. Why have `byte` in the 
language if `char` works like an integer? Ideally ops like 
addition would allow one operand to be a character type, but 
require the other operand to be an integer - that is a useful 
operation, unlike adding '+' to 'Z'.
