shiftL has the wrong type: Bits a = a - Int - a
so it is expecting the value in the IORef to be an Int.

All, what is wrong w the below code?
I get an type error related to the operation shiftL
import
Can I easily fix the modifyIORef statement by swapping something ?

Replace `shiftL` with `flip shiftL` and change the type signature of
`sLbitfield` to take an Int instead of an Integer.
