There is currently no way to know whether or not calling
Data.Bits.bitSizewill crash your program.
I propose extending the Bits class to include:
hasBitSize :: Bits b => b -> Bool
I'm in favor of changing the type of bitSize, although since none of
my code uses that function it's an easy position for me to take.
+1.  The Haskellish solution would let return bitSize a Maybe.
