All - Today is the start of the formal review of the Variant library by Eric Friedman and Itay Maman. The review will run until Tuesday Feb. 25th. I will be serving as review manager. The variant library offers a simple, type-safe solution for manipulating an object from an inhomogeneous set of types in a uniform manner. Whereas standard containers such as std::vector may be thought of as "multi-value, single type," variant is "multi-type, single value." This reduces code duplication and enhances maintainability. You can obtain the latest version of the library from the boost-sandbox or from: http://groups.yahoo.com/group/boost/files/variant.zip Please state in review comments how you reviewed the library and whether the you think the library should be accepted into Boost. Further guidelines for writing reviews can be found on the website at: http://www.boost.org/more/formal_review_process.htm#Comments Thanks, Jeff
