Re: [Boost-users] [boost-users] [general question] deciding to use member function or not.

I believe you can't do it in a generic way for all the classes. But if
you design  your classes with support for concept_check ( see boost
concept check library for more info ) you can get pretty close. If C++
gets reflection support in future(hey it doesn't cost anything to
dream!)  this can be even done at runtime.

Thanks,
Edwin
