src/Main.hs:107:19:
    Could not deduce (Num a) arising from the literal ‘15’
    from the context (Bits a)
      bound by the type signature for highNibble :: Bits a => a -> a
      at src/Main.hs:106:15-32
    Possible fix:
      add (Num a) to the context of
        the type signature for highNibble :: Bits a => a -> a
    In the second argument of ‘(.&.)’, namely ‘15’
    In the first argument of ‘(.)’, namely ‘(.&. 15)’
    In the expression: (.&. 15) . (flip shiftR 4)

    Could not deduce (Num a) arising from the literal ‘15’
    from the context (Bits a)
      bound by the type signature for lowNibble :: Bits a => a -> a
      at src/Main.hs:109:14-31
    Possible fix:
      add (Num a) to the context of
        the type signature for lowNibble :: Bits a => a -> a
    In the second argument of ‘(.&.)’, namely ‘15’
    In the expression: (.&. 15)
    In an equation for ‘lowNibble’: lowNibble = (.&. 15)
