Oh I missed this :( I just tried your newer version and it works. Do you plan to support this also for C++03?
No.
I'm pretty bad with Boost.Preprocessor but I suppose it'd be doable with a max number of arguments, right?
Before I plan another useless workaround, do you plan to support anytime soon rvalue references in the concept map definition? It'd be something useful.
I don't know exactly what you're referring to. I don't remember off hand how complete my rvalue reference support is. I'll try to finish it off after I implement a variadic BOOST_TYPE_ERASURE_FREE.
I mean something like this in a concept map: struct any_foo: ::boost::mpl::vector< has_foo<void(Something&&), const boost::type_erasure::_a> ...> {}; This would avoid some very dirty workaround I am seriously considering.
