Oh, that's something I haven't thought about. There are quite a few places in boost where inheritance from generic types is used, presumably they've all got the same problem. I'm not sure if there's a good way to handle this.

Can't you just wrap it and derive from the wrapper? For instance, I have a wrapper (which is a little overkill for this) at ebo_wrapper.h https://github.com/nliber/cool/blob/master/ebo_wrapper.h. My version uses the traits in std, but Boost.TypeTraits https://www.boost.org/doc/libs/1_66_0/libs/type_traits/doc/html/index.html has equivalents. -- Nevin ":-)" Liber > +1-847-691-1404
