[fusion] Fusion using varidiac templates
hi, I remember seeing that there was an initial port of fusion to use variadiac templates a while back. Is that code available somewhere? If so, where could a find that? Thanks, Paul

http://ch.ristopher.com/git/?p=slim Aside from the different namespace Slim should be pretty much source compatible to Fusion. I renamed the namespace because I don't want to continue to provide patches for Spirit and Proto any more - both libraries rely on Fusion's internals, Spirit even on undocumented parts, and won't work out of the box with the port. You can use Slim and Fusion side by side. You should be able to switch between the interfaces without problems, that is, you are able to call Fusion's functions with Slim types and the other way round. Check <slim/adapted/fusion.hpp <slim/fusion.hpp> Christopher

A variadic fusion sequence is easy-peasy. I have one implementation here that would probably go into the codebase sometime in the future. OTOH, your std c++11 library should probably have a variadic-savvy tuple already if your compiler supports variadics (g++ does, MSVC doesn't (yet)). Right now, fusion supports std::tuple as-is. You can use your std::tuple just like any other fusion library. Simply include fusion/adapted/std_tuple.hpp and you can use it just like any other fusion sequence.

Actually, I was looking for it, more for the functional parts of fusion(ie invoke, fuse, unfuse), than the sequences, since as you say std::tuple can be used in directly in fusion. ----- Original Message -----
