[1 of 3] Compiling IPv6Addr         ( src/IPv6Addr.hs, dist/build/ip6addrcan/ip6addrcan-tmp/IPv6Addr.o )

src/IPv6Addr.hs:220:36: error:
    • Could not deduce (Eq b) arising from an operator section
      from the context: Num b
        bound by the type signature for:
                   firstLongestZerosRunIndex :: Num b => [(Bool, b)] -> b -> b
        at src/IPv6Addr.hs:218:1-61
      Possible fix:
        add (Eq b) to the context of
          the type signature for:
            firstLongestZerosRunIndex :: Num b => [(Bool, b)] -> b -> b
    • In the first argument of ‘takeWhile’, namely ‘(/= (True, y))’
      In the second argument of ‘($)’, namely
        ‘takeWhile (/= (True, y)) x’
      In the expression: sum . snd . unzip $ takeWhile (/= (True, y)) x
