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.
The library provides a generic representation of type-indexed abstract syntax trees
(or indexed data types in general). It also permits the definition of open syntax
trees based on the technique in Data Types à la Carte [1].
This package does not work on GHC version 8.2, but works on many
earlier and later versions.
(Note that the difference between version 2.x and 3.0 is not that big. The bump to
3.0 was done because the modules changed namespace.)
