Hi,

I am trying to transform from a fusion vector of values to a fusion vector of non-const references to those values, the ultimate aim being to assign the original sequence from another sequence.

The code below works ok with make_vector, but I want to be able to automate it for any fusion sequence. How can I do that? You can find an example of exactly that on the zip_iterator_fusion branch of boost/iterator/zip_iterator.hpp

Yikes. I don't really understand what I am meant to do with that. I will have to study it in more detail. I reckon that a get_ref_vector(fusion::vector) would be quite useful. I guess there isnt much difference to a view though?. Anyway I have continued hacking away and so here is my latest efforts, using fusion to do a dot product of two vectors. Maybe it would be a useful example in the fusion docs?. Anyway here it is FWIW:

Yes, definitely! I'll have to ask for documentation though. A simple readme file is ok, plus, lots of comments. Regards, -- Joel de Guzman http://www.boost-consulting.com http://spirit.sf.net
