libghc-stmonadtrans-dev - 0.4.8-1 main

This package provides a monad transformer version of the ST monad.
.
Warning! This monad transformer should not be used with monads that can
contain multiple answers, like the list monad. The reason is that the will be
duplicated across the different answers and this cause Bad Things to happen
(such as loss of referential transparency). Safe monads include the monads
State, Reader, Writer, Maybe and combinations of their corresponding monad
transformers.

This package provides a library for the Haskell programming language.
