But Ada already has these things for modular types (and for
packed arrays of boolean, which is really a higher-level feature),
so why do you want to create such a library?

By the way, since we're arguing about terminology, I do not consider the
shift operators to be "bitwise".  To me, the bitwise logical operators
are the ones that operator independently on the bits of an operand (for
"not"), or corresponding pairs of bits (for "and", "or", and "xor").
In other words, the value of bit number N of the operand(s) affects ONLY
the value of bit number N of the result.
