[Haskell-cafe] ANN: bimap 0.1 - a bidirectional map

Data.Bimap is a data structure that represents a bidirectional mapping between two key types. A bimap has two type parameters; each value in the bimap is associated with exactly one value of the opposite type. In other words, it's a bijection between (subsets of) its argument types. The API is loosely based on Data.Map; feedback and suggestions are most welcome. So far I've only tested it on GHC 6.6 on Linux/x86, with Cabal 1.2.3.0. Let me know if it works or breaks on other configurations.
