The keyed package

[Tags:bsd3, library]

This library provides generic indexing for a number of data structures, so that we can overload (!) in the same way we overload length with Foldable or (f)map with Functor.

Readme for keyed

Readme for keyed-0.3.0.0

This library is simple enough: it provides overloaded functions for indexing data structures.

In Data.Keyed, we provide functions for pure data structures that return the contained values unwrapped.

For example, you can do [1,2,3] ! 2 or Map.fromList [(1,'a'),(2,'b')] ! 1.

In Data.MKeyed, we provide functions for data structures that return the contained values wrapped in a Monad (like IO, ST, or STM) or other container. This module is highly experimental, and it may change to improve interoperability with certain libraries.
