Personally, I did not really notice your announcements. Some time ago I wanted a dynamic type-indexed container, in which you specify the required type, and it's either returned, or created. After quite look on some email of yours I decided it's something different and stopped reading. Now I think that using associative_list in BGL is desirable. (BTW, looks like with a little tweak I can achive the desired on-demand creation using your library, too). > a) The library is not something that people think makes sense in Boost. > b) The library uses the wrong approach to the problem and someone should > submit something else. > c) The library is not something that anyone would really use.

So true! However, I'll do my best to look at your library in detail during this week. - Volodya _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
