Hello,

Boost.Bimap is in beta stage!

Boost.Bimap is a C++ library that will probably be included in Boost ( www.boost.org )

The project information, docs and sources can be found here:
rojects/boost_bimap.html...

With Boost.Bimap you can create associative containers where both types can be used as key. You can think a bimap as a merge of a std::map and a std::map. The learning curve of bimap is almost zero if you know how to use standard containers.

The original project that encompasses the creation of a one to one bidirectional map has been extended into a framework that extends the standard mapping scheme. A bimap is a very flexible and powerful container, but the interface of the library allows a user to use it out of the box.

Looking forward to getting your feedback,
Matias
