Hi, in my project I do have a lot of fusion adapted structures (due to use for/with spirit). Now I want to compare them. How to reuse the informations? In the example attached, I show the (imo) complicated way using fusion::vector_tie. I would like reuse the BOOST_FUSION_ADAPT_STRUCT macro since it generates tag_of<>, struct_member<>, struct_member_name<> , struct_size<> etc. At http://www.boost.org/doc/libs/1_42_0/libs/fusion/doc/html/fusion/extension/e... there is the full blown feature shown how to adapt the structure for a fusion iterator. What do I really need for simple comparing? Is it the way to use? Even simpler one? Since the project is involving, a simple and && combine of the members isn't save - easy to lost one ... Thanks, Olaf
