You have to know the type of the vector at compile time.
Even if I know the type of the vector at compile time, how could I create the fusion vector incrementally from the variant? Since push_back always returns a new type, I don't know how to do this with a visitor.
I was also talking about "chopping" the variant in disjunct sequences. By this, I mean that a visitor goes over the variant and creates several sequences, say
[42] [4.2, 42] [42]
I think the easiest way is probably to create a runtime iterator that walks over the vector and recurses into any variants that it contains.
Then you can use fusion's algorithms to iterate over the fusion::vector and the vector in parallel.
I'm not sure if I can follow. If I start with the variant and have some plan to partition it into sequences, how would I use an iterator rather a visitor? Would you mind illustrating your idea with a small code snippet? Matthias -- Matthias Vallentin vallentin@icsi.berkeley.edu http://www.icir.org/matthias
