spiderx@spiderx.dp.ua Vladimir Pavljuchenkov proxy-maint@gentoo.org Proxy Maintainers In Haskell you very often acquire values using the with... idiom using functions of type (a -> IO r) -> IO r. This idiom forms a Monad, which is a special case of the ContT monad (from transformers) or the Codensity monad (from kan-extensions). The main purpose behind this package is to provide a restricted form of these monads specialized to this unusually common case. managed Gabriella439/managed
