Hey, I see that this discussion is heading somewhere towards the support for graphics programing (which is a good thing ;) ), but as you were looking for ideas, I thought that I'd mention one other thing which I'm sorely missing in C++ - a good (prefferably mirror-based) reflection facility/library. One that would be supporting both compile-time and (at least partially) dynamic reflection of base types, functions, their parameters, return value, structs, unions, classes and their base classes, attributes and member functions, also the "special" ones like constructors / destructors, instances, variables, and so on. Reflection can be a great tool when doing certain kinds of things, especially persistence-related, like (de)serialization in multiple formats, (de)marshalling during RPCs, but also as a support for scripting, virtual construction, object inspection, custom debugging and much more. In the proces of developing my own reflection library few years ago, I learned that designing such a little-more-than-basic-facility is quite difficult, if you want to reflect more than the types, simple classes their attributes and member functions. Problems start to arise when one is trying to reflect containers, objects behind interfaces (like an implementation of a xml document, or a stream, for example) or objects behind one or even behind multiple proxies and when trying to serialize or send such objects over a network. With such classes/objects it is not obvious what to reflect, the internal implementation, it's public interface, one of it's proxies or whether to allow to switch between these meta-classes. This depends on the context. The implementation of mine partially addressed some of these issues, but it uses many things, that are not implemented in the boost libraries, which I had coded myself and it definitelly needs a major or possible complete redesign and rewrite. Unfortunatelly "they" ;-) want me to finish my PhD thesis so I don't have much free time right now to do that. But I would be glad to lend a hand in the near future and offer my humble expertise in this field if there is any interest ;) I'm aware of the boost.extension/boost.reflection project and as http://boost-extension.blogspot.com/2008/02/back-at-work.html claims, the show is back on the road again ;) so I'm definitelly looking forward to see some progress here too. best regards, -- ________________ ::matus_chochlik
