SafeHaskell introduced the notion of safe and unsafe modules.
In order to make as many as possible modules "safe",

This makes it hard to write packages that work

This package provides a single module
that exports the unsafe functions from the base package.
It provides them in a style ready for qualification,

You still have to adapt the import commands.
It uses the
