Well, bitSize is deprecated in favor of two safe alternatives, including finiteBitSize. It is unfortunate that the signed stuff in my default creates a Num dependency--that may be enough to kill it. The case of Integer is pretty peculiar. What do people use that instance for?
Infinite bit sets I guess, I don't think it is that unreasonable to exist, were it not for that pesky bitSize. FiniteBits and that deprecation are GHC specific. Though, it would make sense to port to jhc, it's fairly annoying for portable code to rely on ad-hoc changes like this. Looks like some work went into removing the Num superclass in ghc's base. Hmm... I think type class aliases are needed to actually make it backwards compatible though. Since bit is a primitive, you can get zero from the somewhat awkward 'clearBit 0 (bit 0)' and one from 'bit 1' and -1 from complement zero so the defaults that were dropped can be added back in using those.
