Hi, Please can you add the unordered container library to the review queue. It is an implementation of the unordered containers specified in TR1, with most of the changes from the recent draft standards (it's missing emplace which is tricky). It can be downloaded from: http://www.boost-consulting.com/vault/index.php?directory=Containers Either unordered.tar.gz or unordered.zip - they're both the same. Documentation is included in the download, and is also available on the web at: http://unordered.nfshost.com/doc/html/unordered.html The library has been tested with g++ 3.4, 4.1, 4.2 and Visual C++ 8. In the past it's been tested with some other compilers (intel on linux, borland, older versions of gcc and visual C++) and it'll probably still work on those (I haven't changed much since then). thanks, Daniel
