This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
PEZ is a generic zipper library. It uses lenses from the "fclabels" package to
reference a "location" to move to in the zipper. The zipper is restricted to
types in the Typeable class, allowing the user to "move up" through complex data
structures such as mutually-recursive types.
Both the Typeable class and fclabels lenses can be derived in GHC, making it
easy for the programmer to use a zipper with a minimum of boilerplate.
Please send any feature requests or bug reports along.
