Removing the Num superclass of Bits was also mentioned, but that would need its own proposal.

Ok, I would like to propose removing the Num superclass of Bits.

Would we just remove default methods like bit i = 1 `shiftL` i x `testBit` i = (x .&. bit i) /= 0 ?

The Num superclass is only needed to be able to say 0 and 1. Perhaps we should just add the methods zero and one to Bits?

That sounds reasonable.
