Well, the proper mailing list is: https://lists.sourceforge.net/lists/listinfo/spirit-general
It also fits very well into this thread.
Yeah. You did miss something. The closure members can be initialized. See "Initializing closure variables" section in http://tinyurl.com/85hbq
And, to stick with my example, what would be a good initialisation for a plus_expression? You don't want to replace default construction with a copy from what's conceptionally a default. The topic question of this thread is about whether or not you should construct objects prior to when you have enough information to meaningfully do so, and for returning parsed values in spirit, this is neither at closure contstruction time nor at rule/grammar invocation time. I have the impression that spirit either forces you to do exactly that or else use actions, which is even more messy. Am I correct in that observation? Best regards, Jens
