"Terry G"
I've just finished reading C++ Template Metaprogramming again. I just don't get it.
Should probably not be your first book on template metaprogramming. Really, it's just like trying to learn STL without any idea what a template is.
Why would someone use a type container?
For example, one could implement a generic tuple class (although I don't think boost::tuple uses this approach, but probably fusion does?). Also see below...
I'd really like a reference to an MPL primer or some case studies.
IMO, you should really start with template metaprogramming itself, and then move to MPL. Try Alexandrescu's "Modern C++ design" -- it also contains a lot of examples why you would want to use a typelist. Once you have a basic understanding of template metaprogramming, get back to the MPL book -- it's worth it. Regards, Arkadiy
