Proposal: Add hasBitSize to Data.Bits.Bits

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 such that it returns False for Integer and True for the other instances since the vast majority of instances are finite, it may be reasonable to set the default definition to hasBitSize _ = False Discussion Period: 2 weeks
