Hi Brian, Anyway, I just downloaded the boost version of FC++. I'm just beginning to read and peruse the code. As you surely know, FC++ has been one of my influences. I've studied the code once a few years ago in its early beginnings. And how it has grown! I still have a copy of FC++.1.2.1. I can't say enough how much it has influenced Spirit and Phoenix. Anyway, a quick question before anything else: How easy would it be to decouple the FC++.1.2.1 part of the library (i.e. without the lambda, without the sugar and spice)? If you recall, before Spirit became a boost library, I considered using FC++ in Spirit. One particular thing I liked was its small size. As a library writer myself, using another library, it seems more appropriate to hook into the lower level stuff, which in itself is already quite useful (I recall the exact reals library, for instance; certainly it was written prior to the sugar). I've seen you draw an outline of the basic organization of FC++ as it is now. Which part of this outline corresponds to the old FC++.1.2.1? << BTW, I haven't seen Yannis around in boost? >> Regards, -- Joel de Guzman http://www.boost-consulting.com http://spirit.sf.net
