Is that because bools and chars will be promoted to ints?

I can imagine wanting bools and chars to hash differently, to take 
advantage of their special properties. Then hash_value('\0') could be 
different to hash_value(0), which wouldn't bother me because they are 
different types. However I can understand if this is felt too risky for 
general use.
