[boost] [fusion] More quanfusion

Hi Boosters, Continuing my experiments with fusion, towards the goal of a fusion matrix, here is my latest efforts: Fisrtly I created a fusion advance_iterator (I think it needs an offset to be added which I will do next) Heres an example of use: Select 2 range with advance_iterator and then do the dot product. Also shows use of static values which can be optimised away http://tinyurl.com/zj4uw Second question. I have now created various bits and pieces which seem tailor made for fusion : dot_product aka inner_product static_value advance_iterator. I am not quite sure whether put these into the fusion namespace and put them in the Boost Vault as extensions to fusion, or just to keep them in my own namespace? regards Andy Little
