Voila! The implementation is trivial: one specialization of proto::when on the new (incomplete) proto::external type. God, why didn't I think of this sooner? The naming issue goes away completely. There is no fancy new proto transform to be named. Also, proto::named_rule goes away, too. I'm attaching Thomas' (now laughably trivial) traversal_proto.cpp example, along with my mini Phoenix, both ported to this new scheme. The mini-Phoenix takes the extra step of bundling the actions with the parameters into the phoenix environment (doing the unpacking/repacking under the covers as necessary). One potential further simplification would be to give users a nicer way to map rules to actions. I'll think about it.
This is awesome, Eric! I thought we had a winner. Now you doubled the win! :-) Don't stop! ;-) Regards, -- Joel de Guzman http://www.boostpro.com http://spirit.sf.net _______________________________________________ proto mailing list proto@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/proto
