See http://boost.org/doc/html/array.issues.html : g++ 3.3.3 accepts array<int, 5> a = { 0, 1, 2, 3, 4 }; without complaint when using -Wall -W. Assuming that other modern compilers do too, then this Open Issue should be removed, and the documentation updated accordingly. (Also, the Lambda Doc Bug I pointed out has not yet been addressed; see http://lists.boost.org/MailArchives/boost/msg64450.php .) Stephan T. Lavavej http://nuwen.net
