base-io-access: The IO functions included in base delimited into small, composable classes

[ gpl, library, system ] [ Propose Tags ]

An attempt to break up the monolithic IO monad into small, composable classes that can be used to restrict a function to only having access to, say, functions to work with the standard pipes, or a function that can access the environment. The motivation for this library is to allow people to make a stricter contract than simply "this function does IO", and express through the type system exactly what IO is being performed.
