The parameterization of α and β in Readable and Writable do allow some
nice instances like:
instance Readable (TMVar α) STM (Maybe α) where
read = TMVar.tryTakeTMVar
instance Writable (TMV

Reference is class which generalizes references and monads they exists
in. It means that IORef, STRef and others can be accessed by common

I am glad to announce that LibZip, a major remake of Haskell bindings
to libzip library, is now available [1].
