A typeclass for byte operations?

[Lennart Augustsson]

You might want to make it more general than byte and byte-vector (or
whatever it is you imagine rotating).
The endian problem occurs anytime a sequence of smaller units are
aggregated to a larger unit.
So it could be bits in a word, 8-bit bytes in a vector, nybbles in a byte, etc.
