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.
