Yet how many applications could make use of the limited range that a
1-byte integer type would provide?  Compared to the mess this would
introduce into the resolution of numeric literals and functions, this
seems to be of limited use.  I suggest that you implement this as an
extension module for your own use.

4-bit integers are out of the question.  The architecture doesn't allow
it.
