haskell@gentoo.org Gentoo Haskell Generic support for list-like structures in Haskell. The ListLike module provides a common interface to the various Haskell types that are list-like. Predefined interfaces include standard Haskell lists, Arrays, ByteStrings, and lazy ByteStrings. Custom types can easily be made ListLike instances as well. ListLike also provides for String-like types, such as String and ByteString, for types that support input and output, and for types that can handle infinite lists.
