unsafe is:package

Unified interface to unsafe functions SafeHaskell introduced the notion of safe and unsafe modules. In order to make as many as possible modules "safe", the well-known unsafe functions were moved to distinguished modules. This makes it hard to write packages that work with both old and new versions of GHC. This package provides a single module System.Unsafe that exports the unsafe functions from the base package. It provides them in a style ready for qualification, that is, you should import them by

import qualified System.Unsafe as Unsafe

The package also contains a script called rename-unsafe.sh. It replaces all occurrences of the original identifiers with the qualified identifiers from this package. You still have to adapt the import commands. It uses the darcs-replace-rec script from the darcs-scripts package.

Non-total extensions to the Yaya recursion scheme library. Yaya is designed as a _total_ library. However, it is often expedient to use partial operations in some cases, and this package extends Yaya to provide those operations. It’s in a separate package (and modules) in order to make sure its use is very intentional and also relatively obvious to those reading your code. It’s recommended that you import these modules qualified and, in particular, all the type class instances here have been pulled into a separate module to avoid accidentally bringing them into scope.
