I.e. the problem with the toggles is, that they are toggles only. It is impossible to return both static and not-static members, which especially for functions is useful In general it is impossible to return ALL members, e.g. `boost::mp11::mp_for_each<describe_members<T>>` could be useful, especially for a compiler implementation
I've been thinking about that, and i believe reversing the modifiers could give a cleaner interface for doing it. ie, something like: describe_members<T, mod_filter_none> --> returns everything describe_members<T, mod_filter_no_data_members> --> returns only the function, whatever their visibility is, and whether they are inherited or not. describe_members<T, mod_filter_no_inherited> --> returns only the members (data or functions) that are not inherited describe_members<T, mod_filter_no_static> --> returns only the members (data or functions) that are not static describe_members<T, mod_filter_no_inherited | mod_filter_no_functions | mod_filter_no_static> --> returns only the data members that are not inherited and not static (could be provided as an alias, mod_filter_self_data_members_only) From what i have seen, it may event be built on top of the current describe machinery (there is, i believe, pretty much everything in the details namespace to implement it without touching the macros and the current model).
