T11509_1.hs:53:1: error:
• Can't make a derived instance of ‘SC (Serializable (MyList a))’:
‘Serializable’ is a type class, and can only have a derived instance
if DeriveAnyClass is enabled
• In the stand-alone deriving instance for
‘(Typeable a, SC (Serializable a)) => SC (Serializable (MyList a))’
Suggested fix: Perhaps you intended to use DeriveAnyClass
