... as I would expect many more current users of the venerable boost::variant than of its much younger cousin std::variant.
Why do you expect that and do you think that will stay that way? My personal feeling is that C++17-use is picking up at break-neck speed. For good or for worse, although there appears to be a lot of controversy over a (any) variant [and there are quite some quite different implementations around], the std::variant is the one in the std, which seems to give it a head start. In my view there can only be one objective with boost varant2, and that is if it is decided [here] that it is (much) better than the current std::variant, the C++20 std::variant should be/become the proposed boost::variant2. degski -- *Microsoft, please kill Paint3D*
