It's hard enough getting one's head around the PP lib without having to be an expert in it already. [...] It's a shame, because there's a lot of code that would benefit from the PP lib that almost certainly isn't because of the difficult learning curve.
Learning Boost.Preprocessor is like learning a rather verbose and intricate programming language. It is not really surprising that it can be difficult to learn, although the documentation, at least the parts that I wrote, could certainly be improved. It is possible to implement a language using the C99 (or even the less capable C++97) preprocessor that would be much less verbose and intricate and would be significantly easier to use (see http://groups.yahoo.com/group/boost/files/Order/ for details), but it would come at some cost in efficiency (on some compilers the cost would probably be prohibitive and on some compilers the cost is insignificant). -Vesa Karvonen _________________________________________________________________ Protect your PC - get McAfee.com VirusScan Online http://clinic.mcafee.com/clinic/ibuy/campaign.asp?cid=3963
