unexceptionalio

IO without any non-error, synchronous exceptions.

When you've caught all the exceptions that can be handled safely, this is what you're left with.

It is intended that you use qualified imports with this library.

import UnexceptionalIO (UIO)
import qualified UnexceptionalIO as UIO

You may also wish to investigate unexceptionalio-trans if you like monad transformers.
