src/Game/Chess.hs:245:22: error:
    • Could not deduce (VisualStream s)
        arising from a use of ‘errorBundlePretty’
      from the context: (Stream s, SANToken (Token s),
                         IsString (Tokens s))
        bound by the type signature for:
                   fromSAN :: forall s.

      Possible fix:
        add (VisualStream s) to the context of
          the type signature for:
