I haven't found a function in hackage or in the standard library that takes a list of booleans (or a list of 0s and 1s, or a tuple of booleans or 0s and 1s) and outputs a Word8 or Word32.
sum . zipWith (*) (map (2^) [0..])
I'd turn this into
sum . zipWith (*) (iterate (2*) 1) , but it's probably not very important.
