I don't have a particular implementation in mind but as a general
idea it would make the treatment of Integers the same as the
treatment of the standard-size bounded ints. A possible
implementation might be a stream cipher that uses 128-bit Integers
instead of 32-bit ints (bitwise rotations have been used in more than
a few stream ciphers). For arithmetic purposes, rotation is also
useful for implementing multiplication of finite fields.
Ah, so you want to rotate various bounded integers larger than 64bits?
You can do that without changing Data.Bits at all (crypto defines
Word128, Word192 and Word256 which are instances of Bits).
The LargeWord module in Crypto is very cool. Before this email I did
not know LargeWord defined rotate (maybe it is the version of Crypto
I have--3.03?).
