Most folks here don't know this, but the version of Proto y'all are using is actually v4. (Three times the charm wasn't true for Proto.) Anyway, there are so many goodies coming in Boost 1.44 that think of it as Proto v4.1.
I just posted the release notes for this version to give you guys an heads-up of the coming changes. There are a few very small breaking changes that you should take careful note of. Most of the interesting stuff is in the new features: sub-domains and per-domain control of as_expr and as_child. Have a look. Let me know if you have any questions: Boost 1.44 release notes: http://tinyurl.com/242ln7f FYI, most of these changes were motivated by the Phoenix3 work. That sure is one demanding DSEL. -- Eric Niebler BoostPro Computing http://www.boostpro.com _______________________________________________ proto mailing list proto@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/proto
