Hello, I recently ran into a need to initialize a fusion vector with a single argument which is then used to construct all of the vector elements. For example, something that would allow: fusion::vector<int, float, double> ones(initialize_all_with(),1); // at_c<0>(ones) == 1 // at_c<1>(ones) == 1.0f // at_c<2>(ones) == 1.0; I hacked fusion::vector so that the above works. Is this addition of interest to anyone else? There is another (perhaps more elegant) solution in implementing a new fusion "array" Sequence (one where all element types are identical) which can construct all elements from a single constructor argument, and then using that sequence to do the above initialization. E.g., fusion::vector<int, float, double> ones(fusion::array<int, 3>(1)); ... or (another solution) a make_array function that returns a fusion::vector: fusion::vector<int, float, double> ones(fusion::make_array<3>(1)); It would be great if one of these solutions (or a different solution) were added to fusion. I can take a stab at putting something together, if any of them are acceptable. That is, unless this is already possible in some way that I can't see at the moment :-) Regards, Stjepan
