I propose to add the following methods to `Bits` and `FiniteBits` classes:
class Bits a where ...
bitSizeMaybe' :: Proxy a -> Maybe Int
class FiniteBits b where ...
finiteBitSize' :: Proxy b -> Int
Alternative suggestion for names (I frequently overlook the primes): bitSizeMaybeConst :: Const (Maybe Int) a finiteBitSizeConst :: Const Int a sizeOfConst :: Const Int a alignmentConst :: Const Int a Then we must add mutual default implementations in order to preserve existing instances.
