Hello, I am pleased to announce that Andrzej Krzemienski will be a co-mantainer for Boost.Optional His goal is to (finally!) implement: 1. Move semantics emulation (C++-3 compatible). 2. Function value() from tr2::optional that either returns a value or throws. For those of you who don't know Andrzej, he is the main force behind the standarizaztion of std::optional Once again, thank you very much Andrzej ! -- Fernando Cacciola SciSoft Consulting, Founder http://www.scisoft-consulting.com
