I don't think there will be massive breaking changes anytime soon. I /might/ deprecate contexts, but I doubt I could remove them. Too many people use them. Someday I might come out with a completely different C++0x version of Proto with significant breakages, but until then, I think you're safe. And I might not even deprecate contexts. A week ago I tried porting Proto's examples from contexts to transforms and found they got significantly more complicated. I don't have any definite plans wrt contexts and transforms yet. > So the question is: for a beginner who just started to learn Proto, which > parts > of Proto should be studied now and which are likely to be dropped/changed? > Just > to avoid wasting time learning something deprecated. Despite the fact that they're simpler for some things, I'd say avoid contexts. They won't get you as far as transforms. > P.S.

I just committed a fix to trunk. Thanks for bringing this to my attention. -- Eric Niebler BoostPro Computing http://www.boostpro.com _______________________________________________ proto mailing list proto@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/proto
