I quite agree that you shouldn't do a complete implementation when it's not clear if we'll accept it or not. What I'd like to see is a demo, basically. How about one example of each of several different kinds of hints? We need to get a feeling for what can be accomplished and how messy the grammar would get. BTW, it seems like you are putting in a lot of infrastructure to recreate externally the parse-stack state that bison has internally. Maybe an interesting alternative would be to look at touching that state directly. I realize that bison doesn't consider that part of their official API, but bison is a stable tool and seems unlikely to change much in the future. We could probably get away with it... regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
