type EUnexpectedSum = 'Text "Cannot derive non-sum binary representation instance for sum data type" Source #
Common type error string for when GHC is asked to derive a non-sum instance, but the data type in question turns out to be a sum data type.
No need to add the data type name here, since GHC's context includes the surrounding instance declaration.
